I found elsewhere about the 12 bolt olds only having 8 ring gear bolts.
Close, very close but where the cover bolts on, the flange is round where as mine has 'cut out' all around.big83chevy4x4 said:a quick look at randy's shows that the amc 20 could be had with 8 or 12 ring gear bolts.
i also found a ebay add for this

it looks to have the same rib ahead of the diff cover.
they may have changed the casting to get rid of the rib on later axles.
They're cast in, not welded on. Def cast in.75k10chevy said:
Moser and curries both make good axles for around $2000 but by the time I ship it and pay duties, it'll be £2000 which is about $4000 !4X4HIGH said:
OK, now I'm thinking Oldsmobile 'O' type but with an aftermarket carrier. Jolt any memories?
Again hard to tell everything from your image, but it looks like the cast in "truss" on the underside of yours is rounded, the Olds is straight.
The upper "truss" cast into the housing in the Olds goes into the section that holds the bushing. Yours obviously never extended that far, even if ground down.
Last, the Olds looks like it has the traditional "triangle" identifiers on the lower lip of the cover mounting surface, just like the 8.5" 10 bolt GM diff's used in later cars/trucks. Yours doesn't appear to have any indication of that.
Could be year variants, but I didn't think the "O" axle lasted very long.

Yeah, I was thinking of variants. Not that it really matters now as I've put a Trans Am 10blt under it (or rather I am, if I can source the rest of the brake parts!) but it just bugs me as to what it is!

Oh, well that's easy to answer now. It's a spare part.

Damn....thought I recognised it!
It can go in the lockup with all the other 'spare parts' that'll be useful one day

Do you have any pics of the drum/hub area? Preferably with the drum removed? I want to see if it has that AMC 20 bearing retainer back in there, may be a dead give away.
It's had big Furd ends (Strange Engineering) welded on and what look like Furd 8.8 or 8", 10" drums put on.

Hmm. So how were the axle shafts retained in the housing? I'm guessing it wasn't c-clip.
Though I haven't had it apart it looks like an eliminator. But as Dorian says, they'rew 'spare parts' now! It would be nice to find out but not worth losing any sleep over!

Yeah, but the curiosity would be getting to me. AMC 20's had a bearing pressed onto the axleshaft, that had a bearing retainer that would bolt it down to the end of the axle tube. Kinda like an eliminator kit, only it never had c clips to begin with.
