Prefer 3.73 then. Sure, any sources where I can find one would be helpful. I don't mind rebuilding, but let's first focus on complete carrier.

I found a used differential with 4.3 for sale, any thoughts on this gear ratio, for this car? Seems like a big change. I believe that was equipped for transmission with overdrive. I have 3spd. Don't know if that makes a difference. Right now I'm trying to keep this car rolling and enjoy it for it's standard configuration. Doesn't have to be restored to exactness. With the 315 2bbl, is this gear ratio a good solution? Also, without the potential part in hand, how would I know if it uses the same carrier gasket?

Excellent info and kudo's for the explanation and your perspective. You have a lot of knowledge. As I am a little new to this, I had the same question of several names often used interchangeably to mean the same thing. I really just need the differential then, and I'll seek out 3.73 and keep it the same. Or if I'm lucky enough to find the ring gear and pinion and buy separately.

Thanks Loren, good advice. If I found a different gear ratio 3rd member, will this fit/swap out directly in my carrier? Dodge also used the 3.9, would that be a good option too? pros/cons?

Repairing 3.73 and need help sourcing Ring & Pinion pn 1567900. 315 cu in 3 spd manual. Any suggestions appreciated.
