I purchased mopar offset hangers and offset shackles for a 73 Cuda. I installed them with mopar super stock springs which I was under the impression was a matching system. Now my set up is 2 inches or so too short. Everything bolts up but the rear shackles are all the way forward and the rear spring eye is touching the bottom of the frame rail.
My question is, did I buy the wrong offset hangers? Is there an extended offset hanger for superstock springs on an ebody? Does anyone know the part number if so?

Thanks,

Reggie
