I would do some checking on some dimensions. From the looks of things, someone may have swapped in a 73 or newer rear from a G-body. The brackets the lower control arms and shocks mount to don't look like ANYthing of that body style, 72 and older. Check the date code on the rear housing on one of the strengthening ribs by the cover. measure plate to plate and I'll check my car if needed. You should have a 8.2" rear. I have a feeling that isn't in the car you have there... Theres no reason for the springs to be like that. Something's up... Mike
