Diff experts… which are compatible in first gens?

@6P4 thanks for the reply
I’m in rural west NorCal
So I bit the bullet today I decided to just replace my blown front diff with the stock 3.91s
I scored one for $375 with low miles

My truck is my DD and it needs 4wd again asap.

When I get the luxury (far drive) of checking out some yards, I’ll be looking for that 4.3 elocker or 4.56 open diffs to add an Eaton to.

I did find a complete 4.3 axle for $1250, but it couldn’t be shipped, was like 12hours round trip, and it was rusty. So by the time I got it and cleaned it up it wouldn’t be worth the “good price” to me.

keeping my ear to the ground tho, thanks again
