12 Bolt Carrier? Posi.
No real identifying numbers here that I can chase but this looks like a GM 12 bolt carrier. Maybe ya'll can help. Years, interchange?

EDB 30142 ? Trying to read the last casting number
Not a c-clip axle 12 bolt carrier...
With the shape of the carrier & the 2 spring preload plate setup, believe it is one of the three different ratio 65-70 Pontiac "P series" big Pontiac Safe-T-track carriers. Had these carriers identified by their Eaton casting number, but lost that info with pics on my old Dell laptop when the screen went out. 65-70 Big Pontiac Tech section should be able to ID.

I agree with OPH. Just looking at the pictures of my 68 Catalina posi unit and it's pretty much identical. Only difference is mine says 152 where yours says 148. Which series carrier it is is still in question though. Mine is the first series ( 2.29, 2.41, 2.56 ratios) FWIW.

30148 is the low ratio unit. 3.23:1-up.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.
