Carrier Casting Numbers - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Before I get too deep into this ring and pinion job I want to make sure that I have the right carrier. The numbers on the carrier are 326663N GM 71 C4. I'm puttin in 3:08 gears in the place of my 3:73. This will be my first rear end job, I've done just about everything else, so this is new to me. Years ago when I used to race a buddy and I would just slap in a 4:11 in my 62 Chevy and race. Howled like heck. I think we used rubber bands for O ring seals. We had fun and won a few.
