brake problem: similar symptoms to reaction disk missing
Just in case there is confusion, the reaction disk is a little round chuck of black rubber. Sure you're seeing what you think you're seeing? Take it out and confirm, and then glue it to the end of the steel disk on the end of the rod from the master. Your decription is pretty classic "no reaction disk" so I'm asking silly questions to be sure before you look else where...

Aspirator Fan - how to disable
The automatic air system depends on this little fan to draw cabin air over its adjacent temperature sensor to decide how to manage the overall cabin air flow and temperature. About the only way to have it work without its fan is to reposition that sensor inside the cabin somewhere where its exposed to ambient air temperture, that is NOT affected by the sun, open windows, the direct output of the AC vents, that kind of thing That is why they buried it in the dash and brought cabin ambient air into it via a fan, to avoid all the interfering temperature sources. I'de just let it dangle down in dash, just above your feet, but not low enough to be blown on by any fan driven air. Might have to experiment a bit.

Fusable link upgrade??

Alternator bolts
Sounds like you distorted the holes in the alternator. Start by removing the alternator to get it out of the way, and making sure the bolts still thread into the cast piece on the block. If not you'll need a tap to clean them up. You didn't break one off did ya? If the bolts still thread in nice, the use a drill bit to open up the holes in the alt to allow you to enough clearance to get the bolts back in Of course take a real close look at the alternator and make there is no damage.

Transmission ID - What Transmission Am I "Supposed" to Have?
There is a site that shows the unique case indicators that show if its a 77-78 5sp, or one of the two zx 5 speeds. dual or one-sided muffler hanger castings back at the tail, and long or short ears where the shifter pin goes through. Dual muffler bracket w/ short shifter ears is the 77-78 5sp I believe. Single sided muffler hangers are all zx, long ears make it the 82-83 5sp. (T5 not included in this discussion). This does not help you understand if your car came with a factory 5, just clarifies the origin of the trans you have in there now. Hope this helps

Interior bolts size and pitch
The console bolts (the three in the rear that go in vertically) are 5x0.8, the two glove box lock bolts are 4x0.7mm. You will need to run that tap through with some lube and clean them up, thats all. Hopefully they aren't beyond repair. Wood screws, ouch.....

Aloha, been in Hawaii 8 days,
There is at least one other Z owner on the islands, he's pretty helpful. Trying to remember his name....

280z Distributor, what are the two adjustment screw bolt/thread sizes?
Mostly experience. I also like the game of "show me a bolt and I'll tell you where it came from and what year Z its off of." but that's just me..... Another approach might be to take the dizzy with you to the bolt store and start trying this and that until you find bolts that fit. And SteveJ is dead right, a thread gauge is a wonderful thing. Just remember 12x1.25, 10x1.5 (engine block), 10x1.25 (suspension), 8x1.25, 6x1.0, 5x0.8, and 4x0.7 make up 98% of the bolts thread specs on a Z. What varies is length, presence of a shoulder, strength (grade), head,type, finish, and at least 10 other things.... Happy thread hunting!

Are flares like this done by simply bending metal?
Those do not appear to be the classic zg flares. Much too small and mounted quite low. My guess is custom molded in flares. It does look pretty nice, very subtle...

280z Distributor, what are the two adjustment screw bolt/thread sizes?
The larger one that holds the dist. adjustment plate to the base on the block is 6mm x 1.00 mm, about 15mm long. The smaller one that goes upward, into the body of the dist is 5mm x 0.8mm, about 10mm long. Nothing fancy, common sizes.

Best way to remove front timing cover?
Tip wise, about the only thing I can add is don't forget the two small 6mm bolts that go vertically into the front cover through the two tabs at the front of the head. The one by the fuel pump is pretty obvious but its friend by the dizzy is hiding pretty good, especially if its caked with gunk. And don't forget to put them back in.

When Did They Switch to the Internally Oiled Cam?
No need to pull the valve cover. Open the oil cap and take a look for the spray bar. And for confirmation, get the cam lobe thats right there pointing up and look for a hole in tip of the lobe face.

Hard to start when cold
The mechanical fuel pump is the fault. weak when cranking, takes forever to pull fuel from the tank. This is likely made made worse by a weak check valve in the pump that lets the fuel drain back. The pump works adequately when the rpms are up.

Nut Size?
Most 3mm bolts are 0.5 mm pitch. I have a couple of old grills that I haved used for parts in the past, I'll look and see if I have any of those bolts. Do you need the ones in the center or at the ends? An alternative may be to get some 1/8" brass or soft steel rod from a hobby store or such and thread the ends for #2-54 nuts or something like that? Maybe someone like McMaster car has 3mm all-thread!!!! just checked. Sure as heck McMaster car does have 3mm all thread in steel, brass and SS none the less!!!. 1 meter long in brass is $12.69. That place is amazing.... Just search for all thread, then look at the low strength. They probably have it grade 10.9

Cowl Grille corner rubbers
Never seen them advertised. Only ever seen two pair on real cars, both 75-78 280Z here in Canada. Good luck.

Hatch Hinge Seal Covers
A reliable source for these things at last supercedes any rule breaking! Thank you! Thank you! Thank you! Might want to put a For sale ad in the classified section, just because... We don't have a vendor forum like hybridz... Don't forget to tell them too...

Lost original key with no spare
the key code is also located stamped into the passenger door lock cylinder (assuming it hasn't been changed...). Not the easiest to get to, but good to remember!

They are totally different, no fitty. I have a couple of used ones in decent shape if you get desperate. Catch me at z240@shaw.ca

Maybe im stupid but i can NOT find the rear brake bleed nipple on my 71
To clarify psdenno's statement, the drivers side (Left) rear is the farthest distance from the master due to the location of the T in the brake line back there (right side). It pretty doesn't matter which rear side you start with, I've never had trouble either way. Keg, go ahead and bleed the others, and keep your fingers crossed. Its Christmas after all!

Can a tachometer effect your ignition?
Please tell us what distributor/coil system you're using (240 points, 280 reluctor, 280zx E12-80/92 or aftermarket) and if you have the stock 240 tach. If you have a stock 71 tach then the power to the coil runs through the tach, making it pretty tricky to just have the car run with the tach disconnected. So, as a first and easy test, disconnect EVERYTHING from the + side of the coil, and connect a temp jumper wire from that post to the + side of your battery thus eliminating the tach and regular power supply to the coil. Do this JUST before you start the car, and go for a drive. Note that turning your ignition off will NOT cause the car to quit, you'll have to remove that jumper to get it to stop. Let us know what happens.

Snow tires
Can't imagine anyone here recommending you drive your Z in the winter. Its a garanteed way to have it rust to nothing in record time destroying you dream machine. That said, they are quite capable handling winter cars when wearing good winter tires, so if this is your only choice of a car to drive, then get some good Michelin X-ice or similiar and have fun! Just remember the heat and defrost power of the HVAC system is not up to modern standards. Come to think of it, I somehow I made it through several Saskatchewan winters with my 510/610 back in the day, so I'm sure you can too.. Just be prepared to throw it away come spring. Something, none of us want to see happen.....
