1967 12 bolt rear

[bergy]

This rear was in an old drag car. According to the assembly stamp, it started life as 3.55 posi. It does have the traction bar bracket. I took the cover off, and this is what I found. Just judging by turning the pinion - I'd estimate 4.88 gears.

Ring gear interesting with the corner breaks and deburring . No other mfg stamping on ring gear?

That's also going to have c clip eliminators on it.

No other marks that I can see. I need to take it apart.

8 teeth on the pinion, count the teeth on the ring gear and divide by 8... 39 on the ring will get you 4.875

QP is a 3.07 posi, with metallic brakes. First one I've ever seen.

I think Jim Stubbings has had a couple. This one has been modified - perches removed, tubes welded to housing. Not much pitting though.
