The specifics of converting an E Body 8 3/4 rear end housing to an A body 8 3/4 rear end houseing

Hello There FABO

I am going to be converting an E Body 8 3/4 to fit my 1972 duster. I have already done some research and looked through the sticky thread "An accurate 8 3/4" rear axle width list". I wanted to reach out to any members here on the forum who have converted an E body 8 3/4 to an A body 8 3/4 and ask about what sorts of issues you ran into as well as any specific measurements you decided on shortening the rear end to, as well as leaf spring perches locations. I am also interested in what kind of BBP axel options are out there for A body 8 3/4's and what you would personally recommend for this kind of swap. Any and all information about converting an E body 8 3/4 to an A body 8 3/4 would be greatly appreciated. I understand that deciding to use an E body 8 3/4 to adapt to an A body is the least appealing option because of the overall difference in size between an A body rear and an E body rear but its all I got.

Thank you for reading, hope you have a great day!
