Using a 66 A-100 8 3/4 in a Early A body

I picked up a 8 3/4 out of a 66 A-100 Van and want to use in my 64 Valiant, I will change out the center section to a 3:55 gear, it has a 741 case. Has anyone used one of these axles, and if so any advice beyond cutting shock mounts off and spring pad relocation.
