WHAT REAR END WILL SWAP IN MY 1965 DODGE DART

I know this has been asked before but from what I read they all start at 1967 a body width. I have an 8.8 ford with a 456 in my 1965 Dart its way to much for highway. I would like to put a 8.75 in it that might just bolt in or I can weld new perches on . Please give me the low down on year and model or width I need.

Thank You
FYI, Responses above pretty much covered rearend fitment issues.
I just wanted to relay that your wheel/tire width choices, other than stock, will be minimal regardless of what rear.
Currently working on 65 Dart, Magnum V8/4spd. conversion. I bought kit to move leafsprings in to framerails to allow a wider tire under car. Requires welding,moving rear housing perches to 36". For a couple hundred bucks, worth it to me. To have that option.
Just thought I would mention beforehand.
Also just realized your only half hour from me. LOL
