Henry's 70 Dart Swinger

i'm back at it on this car. Transmission finally needs to have something done about it. Torque converter never was right for cam/rearend combo. Cam is cran purple shaft with 280 advertised duration. Need a 2800-3000 stall, and it has a 2000 in it. the rear is a 3.23 in a 489 case. going to 3.73. or 3.91 rear gear.

also finally getting around to replacing the rims (you can tell I don't drive this car much).

question on the transmission crossmember and the trans mount. the trans mount seems to be pressed in or held in by a metal lip. basically there is no way in hell the mount is separating from the crossmember easily. I took the nut off the stud at the bottom, but the damn thing will not come out. I do not have a pic right now. seems like it should just be held in by the stud at the bottom, but no there is a lip of metal at the top that is clamping it in as well. the lip of metal is part of the crossmember. I feel like someone may have goofed with this thing sometime in it's past.
