Which C4 Parts are Interchangeable?

I am a new '93 C4 Turbo Corvette Owner. My question is how do I know which year parts will fit my car. I've read the FAQ and it was a big help but now I want to know if there are some good links to any more detailed information. Thanks

First thing to do is get yourself the Factory Service Manual. It is well worth the investment.

Like is your car equiped with a LT1 or LT5 (ZR1), manual or automatic transmission.

On a separate note who did your turbo install?

You can often find the two volume red-cover factory serviec manual set here in the C4 for sale section or on flebay for less than $100.

You want to be sure and buy the red covers and not the white "pre production" set.

a lot of parts wont cross over; however, you bought a nice vette.

I was thinking about buying it but I need AC down here .

Look for a member PHROGS? he parts out ZR1s and probably could give you a hand on figuring out the ZR1 AC pieces

I contacted phrogs and he had already sold his blower box set. He only had the engine side left. I'm not sure if his engine side ZR-1 blower box half will hook up to the other half of my coupe style blower box.
