We're bringin' back the Flat Tops!

Recommended Posts

If you got a second round of judging in the Stock Class - at a National Convention - that says quit a lot. Great Job!!

Carl is right on regarding if you make through round 1 to round 2 at ZCON you have a very good Z. Judging for a Gold Medallion is always very critical regarding the correct parts, fit and finish. Congratulations for your awards.

Love it!  If Supercuts cannot do this for me, I can fall back on this:

Nice pictures ! I noticed the front bumper is a little extended, and has a plastic spacer between it, als the rear seems to have some plastic between it. Was this normal to the 73 ?

The front bumper in 73 was extended slightly to add minimal support making it about a 2.5 MPH crash guard to meet US safety standards. As far as I know the rear bumper was the same as all prior years of the 240Z. Not sure about the little rubber pads on the rear bumper ends, I don't remember those on my 73.

Thanks.  Any guesses as to why the judges seemed tougher this year?

I think the judging was probably pretty fair for the car.  Honestly, we just ran out of time to fix all the small details, and those get noticed.  We were actually taping and repainting the finish on the hubcaps in the trailer the day before the show, among other items.  I know there were a few small clamps missing, some wrong screw/bolt heads, the ends of the bumper finishers (unique to the '73) had some cracks and could have been finished better, I need to find some of the pre-formed hoses for the engine bay as the bends in my substitute straight hose showed some kinks, I installed the long plastic edge finisher just behind the seat backwards, the Kioto headlights were the wrong style, etc. Nothing real major, but just not right.  Now that the show has passed, we have some time to fix these items....and a chance to eventually see the judging sheets.

The only thing that bothered me was that the judges were critical of the cloth wrap 'style' fuel hoses.  Apparently they prefer to see a Nissan stamped fuel hose, over a hose that looks very close to the factory original.  This was actually a point of discussion among a group of us, including judges that said the original cars never had cloth wrap style hoses.  Fortunately, Jim Fredricks showed up to set the record straight and confirm the cloth wrap style.  It was great talking with Jim at the show, he schooled me on some of my fastener zinc color errors.  Overall, I am very happy with the outcome and really enjoyed the show.  I am looking forward to going to Nashville next year and seeing the cars from the east coast.

Hi all---

Sorry not to have replied sooner---I was immediately back at work and had to travel to several states for several days after the show.

Missed so many of you, good friends!!

I can't begin to tell what an honor it was to compete with Rich's immaculate fresh restoration of Bob's (Jayhawk's) Z. Rich is a master and a gentleman. His meticulous attention is preserved as archival documentation in this thread for all to see and emulate.

As I conveyed in a PM to Rich, I had always wondered how a "rolling" restoration would fare with a fresh restoration done very well. I feel those hopeful thoughts are somewhat vindicated and I am  relieved now that it is possible.

I have always thought (and think Rich would agree) that the stock restoration of a 73 240Z was one of the most difficult challenges of all due to the many unique differences found in that particular model year. (bumper rubber trims, flat-top carbs, emissions, hoses and water plumbing, thermostat housings, electrical relays and switches, cigarette lighter, etc., etc.)

The chance to compare, apples to apples, 2-73 240Z cars at a Zcon was huge for me. Rich and I shared several corrections that we each made to our cars before the judging. It just doesn't get any better than that in friendly competition!

As Rich said, had he more time and a few parts the outcome could have well been reversed. We both made bonehead mistakes which we have learned from and will try not to repeat.

This Zcon was so special in so many ways.

Big Congratulations to my dear friend Jim Smirlies (S30driver) for his 1st place in daily driver. Fiona (his 77 280Z) never looked so beautiful since I have known him (and her). 

I wish and wish that those of you that we not able to attend the Branson event will attend and be seen at Nashville!

It is just 1year and 2 months away----Let's GET READY!!!

Ive been reading this thread for several days and am amazed by all the knowledge! I'm restoring a 73 with flat tops (which BTW I didn't even know the right term for until about 3 weeks ago) and have had a difficult time finding rebuild kits. I found some from thezstore.com but they seem to have one of the key components missing. Don't I need the metal disc in the center of that diaphram? Is there some other source or solution?

 

Thanks in advance for the help!

Yes you need that little metal disk. In fact, there are disks on both sides of the diaphragm. You are supposed to just pry the disks off your old diaphragms and move them over to the new ones.

Are you saying that you don't have them at all? Or are you saying that your disks are glued onto your old diaphragms so tightly that you didn't know they came off?

That's great info! I have the one on the left and I pried on it a little but couldn't determine if it came apart. I will pry a little harder. 🙂

Thanks!

Yeah, it's just glued on from the heat and the petrified old gasoline. Razor knife works well since you don't have to worry about ruining the old diaphragm. Don't bend the disks.

If you can't seem to get them apart and are worried about bending a disk, you can drop the whole thing into a sealed cup of carb cleaner. For a week.   LOL

Rich where did you get the Tune-Up Emissions decal on the hood, 1973?

Got the emissions decal from Zedsaver.   Not sure if I am very happy with it, but also not sure about what other options are out there.  The material seems to be very thin and was difficult to work with.  Once applied, I used a credit card to smooth over the bubbles that were formed, moving them towards the edges (kind of like burping, I guess).  bubbles that remained and would not move out were popped with a pin, then smoothed with credit card.

Was the material similar to a sticker with a self adhesive backing?

It was like a very thin metalized plastic, adhesive on the back

Thanks for the information Rich.  I'm going to look into having some exact 1973 decals made.  As long as they have an adhesive backing, installing them would be very similar to installing window film.  Use a mild soapy solution, once positioned where you want it, use a firm rubber squeegee and there should be no bubbles (as long as you cleaned the lint and dust off).👍

Sorry to seem so dense, but I just want to be sure I understand correctly. The disks themselves don't really come apart (into 2 pieces) right? Ive pried on them a little but they seem to be machine pressed together. So you're saying to just remove the rubber from the old diaphragm and try to get the disk into the center of the new diaphragm? The new diaphragm doesn't seem like it will flex enough to go over the disk without tearing?

The two discs should come apart.  Best to soak them in carb cleaner fluid or similar then separate them with a razor knife.  Don't worry about damaging rubber, that needs to be replaced with new rubber.

What he said. There are two completely separate (identical?) disks. I'll see if I can get a pic of the parts and post them.
