rear axle identification

Can anyone tell me what this axle is, 8.2, 8.5, BOP or chevy?

 

check Buickperformance Georges web site. Has very good info on axel ID

 

Here is the link. He has a lot of very good info

I call it 8.2 because of the bracket the brake line tee rides on.

If it has c-clips it is a chevy style.

If it has bolt-in axleshafts its BOP.

shoot pics of the pinion yoke and the ends of the axletubes and we can be more definitive.

 

I will have to also agree - Same reasons Very good ID. Pinion nut 1 1/8 it is for sure a 10 bolt 8.2 chevy and c-clip axles

I was able to find some numbers on it today. On the pinion side on the lower flange pass. side says GM 66, the other says 3969277NF. On the back side on the lower flange pass. side says K 51, other side says 490120 maybe and on the same side on the axle tube it says 07-880.
