Which rearend do I have most likely?

I have 73 Buick with turbo 350

 

Well being the smaller engine option... 8.5 is what I would go with. If you have pictures we can I d the rear. Need rear cover and some surrounding area of the casting. Jim

 

Could be the 10 bolt cover 12 bolt gut rear too. 8.75 rear.

 

thanks.. I was hoping they had standard plain jane rears. no pics at this time.. you guys are great preciate it.

 

If it is a weird 10 bolt cover with 12 bolt gut rear...you can not get gears for it through the after market. Hope it is a 8.5 for you. Jim
