My advice? Concentrate on the '87. They weren't made in '88.

You are right. From what I could dig up, looks like they may have produced 922 units of these colors in '88, but they were Sport Coupes and Sport Coupe Convertibles.

Re: Looking for '87 or '88 Yellow/Gold 5.7L IROC-Z
I would look for an 85. Unless you get a 5 Speed 87 or a 350. The automatic 305 only got 190hp from what I have read. The 85 TPI had 215hp. I could be wrong. Anyone heard otherwise?
