Camaro rearend decoding
 

I have what I believe is a 1968 camaro 4:10 rearend casted on October 5 1968. The build date and axle code is QA 0125G. This would have been installed in a early 1969 camaro? Only info I can find is BV for 4:10 in 1969.8 https://www.yenko.net/ubbthreads/pics...9-img_5131.jpg

Something does not jive though. That code was not offered in 69 in a Camaro according to the chart.

That's the link I was getting my info from. Only thing I can come up with is because it's an early 69 build they used the 68 code on the 4:10 gear?? It would have for sure been installed in a 69. It does not have the 4:10 in it now but has a 67 3:31 posi unit in it. https://www.yenko.net/ubbthreads/pics...2-img_5118.jpg

Probably cast Oct 66. 6, 8, 9 can all look the same sometimes... can be pretty rough and difficutlt to distinguish.

66 casting makes the most sense. Assembled January 25. So if it went into a 69, it wasn't an early 69 by any means.

Even Oct 66 seems odd. They are NORMALLY cast and then assembled closer together than Oct. - Jan.

Most 68 4.10 rears are coded BV, just like a 69.

I would be sandblasting that casting date to see if it has been messed with.

It's for sure a 68 casting. I always heard parts can be up to 3 months out. It's been sitting in a garage for over 20 years. It has the original drums still on it. Maybe a dealer installed the 3:31?? Im thinking it's one that slipped through because it was early 69

The QA code matches up for a 67 4.10 posi according to Colvin's book...page 314.

It isn't so much the casting that is the problem for an early 69. It is the assy stamp. They did not use QA for 69. Even if one is thinking early in the model year, using a left over 68, it would still be a BV stamp. Certainly not left over in ;ate Jan. of 69, approx. six months into production.

Ok thanks! So it's probably a 68 rearend then your thinking? The casting looks like an 8 but maybe it is a 6?? I'm looking to sell it but don't want to mis represent it.

Sorry 67 rearend
