TRS = 3.07:1

I use a redbook for reference, but this site has the info.

36 years ago it was anyways.
Why not remove the cover and check? The oil probably needs chainged anyways.

I did pull the cover and it's a 3.07:1 with a posi. I just want to know what the numbers mean.

cool, usually that's why ppl ask, to get out of servicing the rear end. You know, outta sight, outta mind.

Did these trucks have 3.08 or 3.07 gears?I thought trucks 12-bolts had 3.08 and cars had 3.07.

I think it's about how you round the numbers when you divide.

no, there is a 3.08, that was for cars, and a 3.07 that was for trucks.
