GM rear gears

That axle could also be from a 69 Camaro. They started coding the 3 letter rearend codes in 1970 model year and many of the late 69 Camaros got it.
I believe that gear was available over the counter and the dating kinda confirms that. Several unusual ratios were sold over the counter and never in a production vehicle.

Marlin,

Are you familiar with Coupe Chevrolet? My father started working there in 1970. What was the name of the used car lot that sold the HO Y-Camaro?

As for the OTC gears, I have found a set of GM OTC 4:11 gears for a 3-series carrier dated 1968 (I think).

So the choice now for the clone is which gears to run in the Nova? Anyone know about B-M camshaft options?

I never heard of Coupe Chev. The used car lot in Flourtown that sold the two '69 Yenko Camaros was called Ed Dewan's Performance Cars.

Coupe Chevrolet used to be in Glenside, PA until 1969. They then moved to Flourtown (the next town over). My father knew of Dewan's. He said they had all of the higher end hot cars. It wasn't much of a used car lot- everything was inside- more like a showroom.

As for those 4.33 gears, I just found out that they ARE Chevrolet gears. They are over the counter (Kurt S. you were right!) They were discontinued in 1981. The previous P/N I posted was found on the ring gear. If it would help anyone, the true P/N for the ring and pinion is 3961430.

I must retract the statement I made earlier about the GM 4.11 gears that were for a 3 series carrier. I checked them myself and found out the previous owner of these gears misrepresented them, they are simply 3.73s.

Thanks everyone!

Just one of those things I remembered looking thru one of my parts manuals.
