HDK coil over system - spring selection

You are right JR, The Motown Missile in 1972 used factory LCAs with coil overs.

What I ( and perhaps JD) meant was you cannot substitute the factory LCA in the HDK coil over conversion ( unless the frame is modified /notched for spring clearance ). There simply is not enough room for a 2.5" od coil spring using unmodified factory LCAs.

We wish you could, be a lot less $$$$

Good catch.
