I have one of those late 69 axles. It does have the 70 casting # on it.
And it has a 3 digit axle code, CBS, which is a 70 style code.

I to have a 69Z 12 bolt rearend that came out of a late Z/28 car with 70 cast numbers. car was some of the last run. The rearend from drum to drum measures the same as a 69 12 bolt. I found it odd.

ED is there a chance of getting the info off of the protectoplate to see if they used leftover parts to finish the last 69 z28's any numbers and dates would help verifiy this

Ed. I went to a swap meet this morning ,picked up 1969 muncie P9R10A= Oct. 10th 1969 M-20 with V.I.N. 29N119544 in a 3925661 case. This trans still has the french locks on the front cover and the part # tag, to me it appears to be original. I have a "build date correct bolt data base" to check for correct bolts for that time peroid (P-number). Hope this helps--Crash

Crash, thanks for the info.....i feel more confident in the trans and numbers that i have knowing there are dinfinitely examples that are contrary to the know fact books. If you can tell me where to check for the proper bolts and markings. I would like to scope this out also........many thanks for the email and info
