The carriers are of different widths. The earlier unit is about 1.5~ - 2'' narrower than the later unit. We were able to bolt the narrower unit on the Jimmy. But we would have had to stretch the springs' width to get it on the Suburban. Since it is not a runner [Salvage Title] we did not try too hard.
Possibly with a long enough farm jack we could have made it fit.
