Deja Vu: 1971 Restoration

    Looks like an exceptionally clean 240Z - always far more fun to work on well cared for Z's.  Somewhat odd to see the bolts for the tie downs sheared off - far more common on the lower bolts on the front fenders..  Bummer any way you look at it..

     

    Yes, it is definitely well cared for, things are coming apart nicely.  Even the exhaust system came out without a sheared bolt head.  That is pretty impressive.  

    Today I pulled the motor, transmission and exhaust system.  The motor is really pretty clean.  I will check through the receipts and see what was done to it.  Obviously the head was done.  Also has a new water pump and looks like a new smog pump and alternator.  I will eventually check the cylinders and see if a block hone and rings would be in order.

    It looks like the clutch and transmission have also had some work done.  There are some markings on the transmission and flywheel that are from a machine shop.  Those both look to be in real good shape and probably just need to be cleaned up

    The fun part in all this is the Z CSI.  Interesting to note what items have been worked on, and which items are original.  All the little details tell a story. 

    Anyway, here are some pictures from the tear down.

    Made a lot of progress this week.  The outside of the car is just about stripped (only a few items left).  I spent most of the time removing items in the transmission tunnel.  I removed the differential, half-shafts and drive shaft.  Also removed the fuel lines, clutch lines, brake lines and parking brake system.  That 10mm flare nut wrench is absolutely incredible and is a must when removing brake lines.  If you use a regular wrench, you will round off the nut flats. 

      I also removed the heater panel and controls, and the radio. I put several layers of blue tape on the center console near the dash and heater panel to prevent scratches.  That area is always a very tight fit  I noticed the heater valve was stuck and pretty corroded.  No problem there as I have an extra (new) one laying around.  Should have the dash, seats and other small items out by next weekend, then it will be time to start the body work.  I will leave the glass in till last the help reduce the amount of dust in the car.  No broken bolts in the disassembly to date.  That is pretty good.  Some pics are below

    That water control valve may be the grodiest part on the entire car Rich!

    I'm enjoying your tear down with photos and eagerly anticipate the put back shots in the future. :)

    Made a little more progress tonight.  I got the dash out.  Woo-Hoo!   I took lots of pics of the wiring as that is a bit funky under the steering column. Also took out the steering column, brake booster and clutch; so now the engine bay is stripped of parts.  I think I just need to take off the rear view mirror and then I am ready to start body work.  I will remove the instruments and harness from the dash and send that out to get repaired professionally.  I will send that up to Just Dashes in Van Nuys.  They did the dash on my orange 71 240 and it looks perfect.  The brake booster looks ugly, but will clean up nicely.  Here are a few pics.

    Rich, if you need a complete heater assembly I have one I took out when I did my HVAC system. It's out of my '73 and it had about 70,000 actual miles of use...no leaks.

    Cheers, Mike

    I like seeing these photo's of what it originally looked like coming out of the factory, can you take any photos of the doors so I can see how the factory placed the clear plastic film and the locations.

    Most of the car is original, however the doors have seen some work done to them.  As a result the plastic is not in great shape.  The drivers side is just a small rectangle near the door handle.  The passenger side is a bit more complete.  I will try and post pics by tomorrow.

    Thanks for the offer.  I think the heater core is OK, but I will check.  The coolant was a very clean green, so I am optimistic.  It just seemed liked the valve was bad and I have one of those already.

    Anyway, the fun part begins soon.  The tear down is not that exciting as nothing is really made better.  Hope to start doing some of the body work this coming week.  That is a bit more useful.

    Great Pictures - keep them coming! The wiring harness on the steering column might be very useful to many in the future as well.

    Here are some pics of the door plastic.  Neither one appears to be original.  I will re-do these when I start doing the interior work.

    Was short on time this weekend, so did not get much done.  I did get the bulging dent taken out of the passengers floor board.  Looks much better now.  Before and after are shown below.  Too often mechanics stick there jacks under the car and just start cranking.  It causes the severe dents seen here.  The 4 pound hammer and 2X4 did a nice job of putting things back close to normal.  I will use a slide hammer to smooth out the rest of the box beam. AAaaahh, and a picture of the twins.

    That's a nice result for your floorboard, considering how badly caved it was.  Amazing what you can accomplish with a BFH and a piece of 2 x 4.  I wonder what the garage guys had to say to the car's owner when they returned it to him after 'service'.

    I have the exact same hump in the middle of the P/S floor pan, with the windshield out of the car I stood on it and did the jump and stomp maneuver, didn't move. I'll have to try the sledge and 2x4.  The twins look good.

    Another possibility:  Princess Auto (aka Canada's Harbor Freight) has a relatively inexpensive hydraulic collision repair kit.  The challenge, I suppose, would be to rig a beam underneath the roof structure that would take the reaction force without creating a matching boo-boo in the roof.  Or maybe you could make a big, temporary hoop structure that encircles the floor, so that the reaction force is taken by the underside of the floor sills.

    Yes, I guess there are a number of ways to attack this.  Hard to say which way is best.  I was pretty happy with the hammer results and it actually came out better than expected.  Also, the floor is in pretty good condition with no major rust, so no need to replace.  Structurally it seems to be pretty solid.  I will work on the drivers side dents this Thursday.  It is dented about the same as the passenger floor pan was.  I also noticed in the pic that I missed a spot at the aft end. I will have to go back and tap that out.

    I noticed the ignition lock was Silver on this car?  I thought the larger black locks came on the 70-71 and then in 72 they switched to the smaller locks due to using the smaller diameter steering column?  At least my 71 has the black ignition lock on it.  Just curious.

    This Z is actually a '72 Z built in '71, so that may explain why it is silver.  I was not aware of the timing of that change, so thanks for the info.  I probably need to contact Mike and see if he can change the title of the thread to read '1972 Restoration' instead of '1971 Restoration'.

    Ah, no worries.  I may be a little off on the exact dates anyway!  I just saw this and went wait, mine is a 71 with a black and yours is 71 with a silver, what gives! :)

    The body work continues:  Pounded out the driver side floor board this evening.  It looks much better but will need some slide hammer work to finish.  There is a small amount of rust through on this side.  Will probably clean up and weld a 2" X 2" piece of sheet metal here.  

    Removed the cowl.   There is a lot of over spray from previous work/paint and a lot of runs in the paint in this area.  Also, I will have to check on the availability of a washer motor cover.  That may be hard to find. But then again, I may have one in my boxes.

     Started work on the right fender.  Tapped it roughly into shape.  The key to bodywork is to get the damaged area as close to perfect as possible WITHOUT the body filler.  Once it is close, then the body filler goes on.  We want to keep that to a minimum.  I will need to go to TCP Global and pick up a small can to finish the fender out.  Will also use this in the back hatch area.

    Anyway, here are a few pics.

    This thread is getting me all hot and bothered.  Siteunseen, the pic of that orange car with black front and rear spoilers with the black sticker on the side is giving me a warm fuzzy feeling. I may want to try that look. It just seems to fit the car while highlighting its natural body lines. I have some floorboards that look like the ones show here and always wondered how I could get them back to the right shape.  This 2x4 idea is just a great idea to try. Seems like their is no down side to trying.

    motorman7, how did you get the dents out of the square channel?  It is covered up from the inside?  Is that the slide hammer job you mentioned?

    Hi Zedyone,

           The sides of the square channel seem to straighten out nicely as they are 'massaged' into shape, removing some of the 'kinks'.  The center part still needs to be cleaned up with the slide hammer as they are still dented inwards.  As you noted, it is covered from the inside and I do not want to put any holes in the floorboard, so I will use the slide hammer.   I did this on my '71 and it came out pretty well.  I know it seems odd cleaning up the underside of the Z, but when I look at any Z it is one of the first areas I check.  Clean frame rails are hard to find now-a-days.

    Rich, thanks for taking the time to respond sir. I appreciate it and I forsee some heavy duty hammer work in my very near future. Mine is not quite as bad as the ones shown but they could use some love.

    Rich,

    I believe Mike @ Banzai is the only source for wiper bags unless someone else started providing them too
