Okay, I don't know if this is a blessing or a curse... I have a salvaged 9 bolt rear end in my possession (2.77 posi disc, without axles or brakes).

I was planning to build a 10 bolt disc rear. I have a 10 bolt Zexel Torsen carrier (but I haven't purchased gears yet) and axles from a 10 bolt.

Can my 10 bolt parts fit and work in the 9 bolt housing and axle shafts?

And, is the 2.77 posi carrier worth anything?

No. Absolutely nothing internal will interchange between them, not one single piece.

Ok, so is this 9-bolt rear worth anything? I know I can get axles for it, if that helps...

I think I can also get a 9-bolt 3.45 posi disc rear end (no brakes) for cheap from a local salvage yard... is that worth anything?

 

Definitely! Any 9-bolt thats not a 2.77 is worth money! They're stronger than 10-bolts.

The 3.45 9-bolt is one of the most sought-after one as far as stock ones go. Even if you don't want to use it yourself, lots of people with 2.77s would love to have that one instead.

Ok, so anyone have experience and advice on how to ship one of these beasties? I mean, they are not exactly mailbox size...

 

Gee, I just realized I have one of those 9 Bolt 3.45 axels in my second Formula...hmmm
