Thanx!

I was looking at that but you didnt have the C prefix codes listed.

I suppose I understand that one should just add the C prefix to the 2 Alpha codes to determine the 69-1/2 codes.

Did you get my emails???

It shows up in the text:
Most of these later axles (10 or 12 bolt) would have also been stamped with the 1970 style three digit application code (e.g. CBT instead of just BT).

I thought it would have been confusing to add the extra codes in the table. But next time I edit that page, I'll try to make that part clearer.

Yes, got your email. Have been doing house projects....

Thanks!
