From what I have read, the Kumho's seem to be a fairly good tire for the dollar. But they come up short in the run-flat capability falling far short of the standards that GM set for the Vette's run-flats.

Okay gmjunkie, got'a know, is that a three speed I see there?

Does look like mine. Here are a couple of close-ups: Pure aftermarket :D tom...

With the cowl system removed you have a big hole at the back of the hood. Engine heat and toxic fumes can exit that hole to the cowl air intake for the interior of the car. Can increase interior heat and introduce bad fumes into the interior. Either put the flapper back and keep it closed or...

The blend info on Freeze 12 is from the EPA web site. As far as mixing refrigerants, you can mix anything you want, but in most all cases it is illegal. Most A/C shops have equipment for only 134a and R12. Those are the two factory standards. They must have separate equipment for EVERY...

Only factory 4-spoke was the 76 Vega wheel. The '73 stock wheel was a 3-spoke. Post a pic of your wheel and we may be able to id it for you. I have an aftermaket wheel on mine that has Duntov's signature on it. tom...

The cowl induction flapper is controled by a switch up above the gas pedal. It is connected to the upper linkage. At WOT it engages the switch which opens the flapper. Also if you have an automatic it is the kick down switch to drop the trans into a lower gear. Look here for more info...

Both are GM small block engines, the LS series. Some are alumn other iron, different cams, C:R, materials, etc. But in a basic sense, the are the same.

Ahhh, springtime and the a/c threads :D Why not just go with 134a instead of Freeze 12? Freeze 12 is mostly 134a to start with. It is a blend of 20% HCFC-142b and 80% HFC-134a. tom...

Only the DFW, Houston, Austin, and El Paso areas have emission testing. But, even in those areas, cars 25 years old or older do not have to be tested. Thing to look out for is the safety inspection. Part of the inspection is to make sure that the factory emission equipment is in place. For...

The VIN is stamped on the transmission, same as on the block.

A lot of people have been using the 3-point system out of the rear of a late model F-Body. Apparently it is a fairly simple bolt in swap.

Ken, Just go ahead and have it judged. It will provide you with a base point for the car. Then you can decide what you want from the car. Maybe a full restoration if the judging bug gets you. If nothing else, you end up with great documentation for the car. A future owner may appreciate...

Per the Corvette Black Book, the RPO ZX2 Convienience Group included dome and courtesy light delay, headlight warning buzzer, underhood light, low fuel warning light, floor mats, intermittent wipers, and right side visor mirror. It was installed on 41,530 of the 53,807 vettes built in '79. As...

The offical one was glued on top of the tank, but the build sheet was a multi-part carbon form and copies were used all up and down the line. Some times, when in a hurry, the worker would just stuff their copy of the build sheet in some unseen part of the car (rather than taking it to the trash...
