CA FREE: 12-Bolt Rear Differential 1977 C10 Short Bed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have the original 12-bolt from my 77. I replaced it with a later model 8.625" 10-bolt since I needed the truck to roll around during the build and the 10-bolt will be better suited to what I'll be doing with the truck (drag racing).

The rear end drove fine, but made whining noise from the gears. I've never disassembled it so we can assume it needs a full rebuild. Brakes are included and are in great shape, and there are shock extender brackets on it as well. Located in Ventura, CA. I need this gone quite soon so if you're interested, let me know!
