NEEDED BADLY! 7 1/4 diff section and pinion gear

Stroker Scamp says there are two different types and I have no idea.

Damn Dodge making so many different sizes :D

This part wont work with those parts but then if you get these parts they will work together but not with that part... :-k

I've received so many PM's from members yesterday that it actually locked up the browser on my phone. If I haven't gotten back to a PM please either message me again or wait a bit and I'll try to answer them all. Right now posting in this thread (or the other one started not by me) might be an easier option.
