Title: I have a 12 bolt question
Post by: docs692121 on November 14, 2007, 01:27:02 PM

I have a multi-leaf 12 bolt posi rear end to sell but I need to know if the following casting number is for a Camaro or not; 3696341NF.

You sure about that number???? I think you may have some numbers transposed.

Maybe it's 3969341? If so, it's either a late 69 Camaro, or a 70-71 Nova axle. What's the axle code and the date?

Yes, that is correct; I was recalling from memory but the number is 3969341NF.
Axle says  C BM 0624 G 2  {3:31 non-posi}; date code looks like B50.

Thanks for the reply.

If that's really the date (06-24, or June 24th), then it's "probably" for a 1970 Nova. The 1969 Camaro didn't start using the 3969341 axle until around the 08A (August, 1969) time frame.

However, I would bow to Kurt's input here if he has more info.

I concur, it's a 70 Nova axle. Will fit fine in a 67-9 Camaro. :)

Thanks for the info guys;
I have had this unit for over 30 years...it currently has a GM high impact 4:88 posi unit with stock axles. The gears still have some of the yellow coating on them because it has not been used hardly any. It has never been welded or cut on. I am ttrying to track down the info I need before I sell it.
