Tranny won't bolt to mount

Hi folks I'm wondering if you guys know why I can't get my transmission to bolt to the mount on the cross member. I have a 67 Dodge Dart, I put a 72 v8 member in it with a 72 318 and 904 tranny. The cross member that bolts to the subframe goes on fine, but the mount holes won't go into the transmission, the transmission bolt holes are roughly 2 inches forward of there the mount holes are. Any ideas? Motor mounts are on correct
