Rearend Width Differance C10 vs C20... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anybody know for sure if the 64-66 C10-12 bolt rearend is wider or narrower than the C20 10 Bolt Eaton rearend?

I just picked up a 14 bolt from a later model Chevy 4x4 and width is 67" from side to side - wheel mount surface.

Thanks!

The 12 bolts from '63 to at least '68 are 62 1/8" WMS to WMS. The Eatons I have aren't where I can get an accurate measurement for you, but I come up with an approximate measurement of 65 1/2" WMS to WMS
