68 nova ss 396 frame mounts

The subframes are all but identical and the 68 stands are actually taller. Sounds as if you have the wrong trans mount or the crossmember is sitting up too high for some reason. Did you put the thick washers back in the subframe when installed? Or did you put the bushings in upside down? If the washers up front weren't put in, it would acyually have given you more troubles elsewhere and more clearance at the back due to the firewall being the pivot point. If the bushings aren't on top of the subframe, its sitting way too close to the floor and you shouldn't have been able to get the crossmember in, unless it was mounted prior to subframe install.

thanks for the input Novamanrick..it does have the thick washer at firewall subframe and will double check all subframe bushings; it has poly bushings at subframe mounts , which.. if anything would bring body slightly higher. if 69 frame mounts are lower , that would worsen the situation. the tranny mount is the standard rubber 1/3/4 high mount...wonder if anyone has had an isuues with the repop 4 speed . big block crossmember hmm..i wonder if 68 uses a taller frame mount if , they have a different size tranny mount

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.

Jason, I believe that is the problem.. the repop crossmember is off centered somewhat.
