I want to change to a b body setup I have the springs and shock plates. The spring perch stud is 1 1/2 inch closer to the front of the vehicle, the springs are the same 58" X2.5" I think it will work if I add a leaf in place of the short cut bottom spring and redrill the post 1.5" back. Whatduya think?
Dakota springs share the same front segment length as FMJ cars, but are 2" shorter in the rear. I did a full isomount elimination/conversion to Dakota springs on a 79 Volare, and long story short, AFTER all the work, figured out an easier way, but only if your main leaf is still good.
Drop all but the main leaf, get a full set of dakota springs (check the door tags for rear axle rating to get dakota springs that are close to what your car has), remove the overload leaf, now you have 3 leafs to replace the ones you removed from your car. You will have to cut off the ends and do some grinding.
You can keep your isomount and use poly cushions, or continue with the early B lower plates and shocks.....
