8.75 rear axle parts needed

Hi all. I have a GM 8.75 (Cover has 10 bolts and ring has 12) open rear end with 28 spline axles and 2.73 gears (15 pinion and 41 ring teeth) and I need some recommendation on parts. From what I have read it is hard to find parts for. I would like to replace the axle bearing and seals if possible Any ideas where I can get bearing and seals kit?
Sorry it's upside down.

 

Try NAPA????

 

Looks like a regular 8.5 10bolt to me the Oldsmobile 10/12 bolt has a round cover with 12 bolt cover and 10bolt ring gear

 

The picture you are showing us is a 10 bolt 8.5 rear 10 bolt cover and 10 bolt ring and pinion gear set.
Please post the picture of the correct rear. 8.75 rear looks like this... yours might have a filler plug hole in the cover also. Trust me it may look the same but I guarantee the covers are different plus the 5 - 7 o'clock casting area you pictures is absolutely 8.5 not 8.75. Maybe you just posted the wrong picture?

 

I have all the bearings seals crush sleeve etc for BOTH rears.

 

Hey,at least with it upside-down,you won’t leak any fluid from the bolt missing.

 

Yeah but the wheels can not drive the car that way...lol I do not think the roof paint will be doing well either.
