Odd diff I picked up 12 bolt ?


Buddy listed a diff for a friend ,  was in a vega race car ... Long story short ..   I bought it .

It's been narrowed up 55" to the outside. 

Unfortunatly , the ID stamp is right were the tubes were welded . 

Casting number on the center section seems to be a partial ..  385298   , couldn't find the date cast code?

Loaded with a 3.07 posi 

and the brakes are larger than I'm used to seeing ? 

Pic is of a 68 Camare drum for comparison. 

Thoughts ??

Those big drums are likely B body drums?

I think that centre housing casting is likely common to all 12 bolts, so that won't help much.

One way to tell, a bit complicated though, is to see if it has the big axle bearings from a B body, which it likely will to go along with the drums.

Date codes on the gear set likely too?

I'll check the gear set  later for codes.   

 

The center section has no ears cast onto it for the upper arms , that I can tell.

If you want to part with it I might be interested.  I have 3.07's in the 454 Parisienne, but wouldn't mind upgrading to posi.  I have a spare diff that I could put the gears & posi carrier into.

Can you see any sign to tell if it was leaf or coil to begin?

It either has to be Nova/Camaro or Impala if it has no ears on top. So any signs of spring perches, leaf or coil should be a giveaway.

No signs of the cast ears, so I'm assuming it had perches, but have been cleaned off for the 4 link mounts. 

I'll look closer in the daylight ...

 

i just am intrigued by the numbers .. 

Gerry's pics look to be the closest for casting # , 66/67 nova .  If that was the case,,, rare piece to have been cut up ..so to speak !
