10-bolt to 12-bolt rear differential, r u sure?
Alright, I've been junky vehicle looking and found a place that had several 70 & 80s type stuff, which would have what I was looking for a 73-80 12-bolt differential for a 2WD 1/2 ton truck with the 5x5 bolt pattern.
I took one home that supposedly had a posi in it (nope, figures) but had what I would call the "BIG BRAKES" on it, larger than the other 12-bolt truck rear end near it.
It followed me home, I pulled it's pan to find a good gear ratio (3.73) which matches what I have in the truck right now with the 10-bolt.
Anyways, I'm still having second thoughts about this thing on whether it's really that much better than the 10-bolt is/was.
So, one big question, since these things are supposed to be a "bolt-in" replacement for the 10, how bolt-in are we talking here? I mean, I want the driveshaft length to align just like it did with the 10. I don't want to have to shorten or lengthen another one, this last one (for racing) cost me a pretty penny that I'd like to keep and use.
I struck out 100% on the 14-Bolt SF with 5x5 (out of a 454ss pickup) those things are impossible to put your hands on, and I need a little stonger solution, like now.
Thanks!
12 bolt parts into 10 bolt
What I've read is that the 12 bolt parts into the 10 bolt solve the 10 bolts weak issues. I have a link about this, I'll find it and post here.

Lots of articles on converting but I never tried it

Even then, my parts still won't fit.
I had read many articles like the one in link posted but never tried the converting to 12 bolt r/p in 10 bolt myself.
Guess anything can appear on net! Sorry, about that!
