I live in Northern Colorado and used to get parts from a place in Loveland called Automotive Past Times. The owner was an Oldsmobile guy and had tons of parts for them, but the place is no longer in business. I have just recently dug my 71 Cutlass Supreme our of storage and have been getting it road worthy over the last month. I was wondering if anybody knows of a place, or person, in Northern Colorado who has Oldsmobile parts. I am wanting a 10 bolt rear-end with either 3:23, 3:42, or 3:55 gears. Right now the car has the stock 2:73 gears in it and feels sluggish since it used to have a 12 bolt with 4:11s, but that was too much gear for a basically stock 350. Any help would be appreciated.

 

Try calling Bill Abel at Western Drivetrain in Denver , he has helped me on some parts and may be able to help you . His phone number is 1-800-595-6042 . BOB

 

I'm in denver and may be interested in your 2.73's

 

Thanks for the number Bob Kelso, I have used Bill Abel and Western Drivetrain in the past, he does great work.

CQR, the 10 bolt posi 2:73 is the original rear-end to the car so I will keep it since the car is a high option car.

 

Well, I have a 12 bolt 3:23 open (non-posi), but of course not in CO.

 

Not a problem. If you run across a 2:73 or taller(<-- Taller the better.) complete assembly or carrier in your search let me know.

 

I just completed a 3;23 posi rearend for the 71-72 Cutlass , it has all new bearings and a new auburn posi , it was media blasted and primed - painted , new axle bearings and seals . It is located in Illinois so shipping would be depot to depot . If you cant find what you want let me know , i am asking $750 plus shipping . I was a 2;56 open and i upgraded it . BOB

 

Bob Kelso, thanks for the offer, it sounds like a great rearend but I will have to pass on it. I am hoping to find something local or I might just do what you did and get mine re-built.
