1970 Camaro rearend

[DAVE H]

First off, a huge thank you to all who responded, much appreciated.
I'm going to take a swing at this, as my friend is a "as-is" flipper and it will be for sale. I'm looking at it first hand today. I enjoy restoration projects and reuniting rare parts with appropriate applications. I'll let ya'll know if I'm successful, he's a tough negotiator.

If he knows what he's got, he'll be asking 10x what he paid for it, but hopefully you can get it...Good luck!

$250 for that is an ABSOLUTE smoking deal - the caliber of a deal that I'd wager only a select few of us might get - Congrats!

I have understood that the Camaro could have a four leaf spring, which determined different perches vs the Firebird which always used three leaf springs (and the shorter perches) - I do not know if the differential housing code changed with the different perches.

This rear was the "performance" ratio offered for the '70 Trans Am and Formula 400;
For the Firebird line this ratio was only available with a posi;
For the Trans Am a posi was standard;
For the Formula posi was a required option with this gear set;
For the both models this gear set could be ordered with the automatic (M40), wide ratio four speed (M20), close ratio (M21; was a required option; M22 not offered).

I hope some of this yammering helps someone.

Did Pontiac use the COZ code as well? Bill

Yup.. COZ was 3.73 posi on Pontiacs also.

The COZ 3.73 12-Bolt was fitted to all '70 Trans Ams with the M21 4-speed, or M20 and M40 cars with the Performance Axle option.

Also available on '70 Formulas. My RA III / M21 Formula has a COZ.

If he decides to advertise it, I'll let you all know. I won't be buying it.
