You could try Doctor Diff. I haven't used him but many people say good things about his products.

I had 3.55 posi gears put in my 8.75 rear end by Dewco in Richmand Indiana, very nice and knowledgable people.

I bought one from Mancini's.  I have no idea who they sourced it from.

Everywhere I've checked wants over $1000 (most want $1200) for a new or rebuilt third member. It looks like my best option is to take one of my existing units and slip 3.55 gears in it.

Thanks for the info. I apprecitate it.

Cass Eslick, well known as doctordiff at Moparts

It looks he got finally his own domain website:

Yes, at 950 dollars he was the most reasonable.

ditto, He built one a for a local customer of mine. I'll use him again if there's another one needed.

I sourced buying all the pieces to build one using my original case, using new bearings, ring+pinions, suregrip unit etc and he was barely above that with an all new case
