Thanks for your help.

Did you ask the boys in Tag Team?

My book has no listing of CU. QU = 3.07 Posi w/disc brakes.
CU may be a listing for '71 and up.

Hopefully, others may chime in here......

This is defintly a question for the tag team maybe the moderator can send it over there.BTW the axel is not mounted in a car.THNX for your input.

Also post the numbers on the Chevelle site - CU was an axle code used on them in the late 60's.
