the numbers I found are...(D26)(GM72)and(3896339 with the letter N underneath the numbers) Thanks again by all means!!
Those look like the #'s off the center section. What does the rear cover look like? Round for a car or Pear/Apple shaped for a truck?
D-2-6= April 2nd 1966
3896339 = casting #??
GM72 = nothing important
The Axle code is on the passenger side front of tube, will be 2 letters, #'s & a letter. Something like this CX 0727 B >>
ProStreet6t9 may know what casting # that is.
