Thanks for all the great info. I thought all aftermarket was for 3 series BOP, i.e. 3.36 and up. If Auburn makes one for a 2.93, then it must work for the 2.78 also. I think it's the same carrier until you get down to a 2.54. That's nice to know.
Brett, yeah I still have Dave's email addy. Thanks for all the info on local businesses. That 79 T/A 8.5 is an excellent unit. you might wanna hold onto that one!
I'm just fishing for ideas right now, cause I'm kinda low on "Green Quarters" if you'all know what I mean! The bird just sits in the garage and I havn't spent a dime on it lately.
If I could score a driveshaft that would bolt right in I would install the 2.78 again for sure. Then I could swap them back and forth.
Someday when money is once again flowing free I'll put in a tranny with an overdrive and use the 3.42 Posi.
