need spring help soon!
havent posted in awhile - not gotten much done. this week am putting 81 trans am subframe in my 57 short bed step side. it will have 94 chevy 4.3 vortec tbi engine with 4l60e trans. wheel base same as before.
PROBLEM: i am putting qa-1 coilover shock/spring kit instead of the original coil springs. i dont know which spring rate to order - 250, 300, 400, 600?
any body out there can help me?
