Carrier Casting Numbers
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.

Re: Carrier Casting Numbers
The 3.73 gear is in a 4 series carrier and a 3.08 needs a 3 series carrier. I pretty sure the tallest R&P for a 4 series is a 3.42 Sean

Re: Carrier Casting Numbers
Did the 3.73 gears come off of that carrier?

Re: Carrier Casting Numbers
If I remember right, there should be a 3 digit number in the casting. 140=3 series and 174=4 series. Sean
