67 firebird rear question

[PeteLeathersac]

If the below linked site is correct, any '67 Ram-Air 400 cars had the 'UT' 3.23 , 'UX' 3.90 or 'YL' 4.33 rears only..

So regardless of the 'N' casting, check your housing stamp and if a 3:55 stamped UW it's a cool rear but not from a '67 Ram Air car..

Weren't the GTO & Firebird 6-Speed showcars built five or so years ago called Ram Air 6 cars?.

The nodular rear was a heavy duty option,but came on a lot of 4 speed cars....really tuff to get,,really expensive if you need one. Ive had 3.55 posi rears, and they werent nodular,they are the top performance rear..and they made Ram Air I birds in 67,,and it would be this type of rear in it, but 4.33s where standard. Has a better 4 pin posi that is heavy duty too...

Hey Eric, I know Pontiac did make the Nodular rears with the N cast in them. I owned a 68 GTO that had one in it. It also was a 3.55 posi. As far as the bird rear, I have owned about a half dozen of them dual bar rears/cars and have never seen or heard of one(nodular rear) in a bird. But, obviously they made them. I just keep on learning.
I assume it must be rather rare...the Pontiac site might be a good source to check. Let me know what you find out, ok. Cool stuff !! Max
