1965 Dodge Dart stock differential advice
Wildcat in Oregon. They were pricy from quotes given to me years ago compared to othere near where i lived back then. In person that may be different.
Ron's Wrecking in WA. They were a lot of GM but had some other makes' cars and parts avaliable. Never dealt with them peraonally.
I am sure there more.
Old car yards down here don't exist anymore after cash for klunkers. Last one I went to was in Ogden, UT.
