I have the exact same rear end.

My tag reads ALMOST EXACTLY what yours does. Here is what mine reads.

WDM-BR 7CD
2.75 9 385A

The numbers mean:

• WDM-BR "model series"
• 7CD means when it was made C=March 7=Year (1977) D=4th week in March
• 2.75 "axle ratio"
• 9 "9 inch diameter gear"
• 385A ????? my 460 is a "385 engine" maybe it means that???
