The tranny mount is the same for all years. The sub frame and motor mounts are different for 68 BB novas. I'm willing to bet if you have an aftermarket cross member I bet the offset is wrong where the trans mount sits. Take a straight edge and lay it across the offset and compare it to an original cross member. I have one I think laying around if you don't have one. I think the only difference in a small block and big block cross member is where the trans mount bolts through it offset differently. The opening isn't oval for a BBC cross member on the bottom its shaped like Talladega speedway to accommodate the offset holes.
