gm 14 bolt rear end housing
GM 12 Bolt
Casting number 1253741 rear end housing is 76 Monte Carlo thats what is in mine
the 8.2 is the weaker of the 2 as the axles are smaller, the 8.5 is a super strong rear end, almost as strong as the 12 bolt.
Yes, that would be the easiest way to find out.
It is the stamped identification number on a 12 bolt rear housing for a Chevy/GMC vehicle that measures 60.625" axle tube end to axle tube end. Mostly truck housings but there are exceptions to this rule.
I dont have a serial number in my BAG (ARTSY GM)! I think Artsy doesnt has a serial number!
10 bolt k 3 casting #1254332 ratio is 2.56 positraction ring is 8.5 inches
1956
There are two locations for the engine serial number on the engine block for the 2001 Chevy S10 GM 4.3 motor. One location is just in front of the flywheel position on the back, top of the motor. The other position is on the driver's side of the rear of the motor just below the manifold cover.
It's an Olds 403.
I have one in my 92 Camaro if that helps you
