- '69 ZL-1 5spd, '84 turbo 6spd
I put a C4 suspension under my '69, and I'm looking to stiffen up the rear. To tell me what springs I'm looking at while wandering around swap meets, I'm trying to find a chart that has the spring three letter broadcast code (not the vehicle RPO code), and the rates. Anybody seen a chart like this?
