Thread: axle tube id?

Tweet

Hi all, i am trying to figure out what rear i have in my car, these are all the numbers i can find

Front of pinion, 388/0042-12/37/gm/065
axel tube CR1220 B

can anybody tell me what rear this is and what it came out of?

Thanks

Can you take a good picture of it from front and back? That will help.

I can tell you it is a 3.08 ratio (12 into 37)

i will get a pic, it has the 11 inch inverted v rear cover, wheel cylinders bolt in place and looks like no c clips, axles bolted in. and it does have a posi unit.

I made a mistake the axle tube code is GR1220 B ,, not cr1220
sorry

Those axle codes generally don't mean much identification wise. They have something to do with the manufacturing process I think. Not sure what you mean by inverted V.

Get us the pictures, they are the only way to know for sure. Without pictures all you will get are wild guesses.
