hello, The tag on my rear 9 inch axle reads -
WDM BZ 8CD
3 50 9 390b

What does this translate too?? Any help would be great, thanks!

The top line is 'bill of materials' for ordering parts, the 3 50 is the gear ratio, 9 means that's its a 9" rear end, and the 390b I think stands for the plant code.
