Hey all I need to know if these perchs are stock or some sort of spacer to jack up the rear, The rear end is all reassembled with cpp tubular 4 link and sway bar, qa1 shocks, and 2 inch drop springs. The car is extremely stiff and seems to sit about the same hieght....

Those risers don't show up in the 69 assembly manual and there is no 68 assembly manual (that I could find). I think there should be a bump under that riser to center the spring. Earlier BOP rear ends used a flat surface with bolt in retainers to hold the spring.
