i took the same springs and put them on a 1970 rr that had never had the rails changed in. and they went right in. thats why im lost when i go to install them in my car. the rear cross member seems to be dead i just don't understand why i cant reach the shackle holes with out moving the holes forward. the springs seem to be short. but if they went right into anouther 1970 rr id say somethings wrong with my frame rails or my shackle mounts. the do sell ones for a station wagon i heard were different. im sure i have the right ones here.
