Cross member exchange

I have a 73 Dart Sport engine cross member. I am considering to install it in my A-body 67 Barracuda (273/4 speed). I am tired of replacing engine mounts every year (has chains and chassis restrainers). The 73 Dart cross member used the "spool" type mounts and also are more secure/safe if the mount breaks. Took some measurements and the connection points are very close. Wonder if I can replace it without any problem. They share the same torsion bars, spindles, etc. By the way the disk brakes kit is the one I installed in the Barracuda.BARRACUDA-67-ALX-2018-07-08A.jpg
