1971 C10 rear differential question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Kiwi · 02-14-2013, 01:59 AM

I own a 1971 C-10 (350 V-8, auto trans, 2WD/RWD, 1/2 ton). The rearend is original and is fitted with a 3.08:1 ring/pinion and a 1-legger "open" differential.

I would like to install a limited-slip differential but do not know what style/type to order? Thus, what is the official designation for the rearend (such as a 10-bolt, 12-bolt, 8.875-inch, Dana 44, or such) and what should I be buying? [Is this differential correct ... http://www.summitracing.com/parts/au...odel/c10-picku ]

Also, what was the number of axle splines (30??) used on a stock 1971 C-10?
