7 1/4 to 8 3/4 in ‘67 Dart

Hey FABO. So I pulled my old rear end out and am getting ready for a swap, 7 1/4 open to a 8 3/4 suregrip (3.73) in my 1967 Dart (318/904). After some FABO research, I wanted to clarify a few things that I’ve read on other posts.

I know I need new shock plates and u-bolts. Is it correct I also have to shorten the drive shaft and replace the U joint? Anything else I’m missing? This is my first rear end swap so any advice or pointers would be great.
Thanks!
