List of suitabale donor cars with 8 3/4 or 8 1/4 rear ends?

You are a Dart Sport right?
I don't know but I think in a junk yard you are as likely to find a Diplomat or Aspen with an 8 1/4 as anything else.
I'm thinking 120 bucks max. Then all you have to do is the mod I sent ya.
Look around for a cop car. It has one for sure.

That's a B body 8 1/4? Looks too wide by the chart then.
If it was an A body for 100 then good deal if what you want.
Can't go wrong. Maybe axel seals. They don't usually go bad.
But for something else, you want something around 54 1/4 flange to flange. Less ok but not much more.
I am running 15 inch tires with heavy springs and that Dip. rear. Works good.
