Looking for Early 1958 3:70 posi

[Jerry DiTullio]

Hi,
I'm looking for a 1958 posi 3:70 rear end. The car was built around 12/12/1957. Does anybody have one for sale?

I currently have a 3:55 posi in the car. Not correct since the car is 4 speed.

Thanks

If you have the proper date why not change the ring and pinion. Posi units with this early date will be very pricey.

The code needs to be AN on the casing (3:70 posi, 58-60, 4 speed) and according to the NCRS judging manual a 3:55 posi was not made for corvette, jusr for powerglide.

Axle "numbers" aren't judged (except for Bowtie judging).

Jerry:

If you are still interested in a correct rearend for your car, you might try Darrell Shepherd. He is not cheap, but he has quite the inventory of dated and rebuilt transmissions and rearends. He might also work out a swap with you for your old unit. I swapped an incorrect T-10 transmission from my 59 that needed to be rebuilt for a correctly dated one he rebuilt. I am not suggesting it was an even swap. I still sent him a sizeable check with my old tranny. But I was happy with what he sent me. Regards, - Kevin
