Hey guys, this is a LOOOOOONG over due project but i currently have a 1974 7 1/4 (BBP) rear axle in my 69 Dart. I have an A body 8 3/4 (SBP)A body rear axle that i want to swap into it. My question is, do all i have to do it get big bolt pattern axles and drums? Also is the drum width thicker on the 8 3/4? My wheels have minimal clearance with the 7 1/4 so just seeing what im in for here. I have also read that the A body 7 1/4 and 8 3/4 are the same width from flange to flange. Is that correct? Thanks!
