Hey Guys I came across this amazing website earlier today while looking for rims for my IROC...I have an 87 with a T-5 tranny and I'm getting ready to swap in a 307 from a 72 Chevelle, all I need is the flywheel. My question is this: Do I need a Flywheel for a 72 Chevelle or should I get one for the 87 IROC? Any help is very much appreciated
