I have a rear end I need some help to ID.
It is a late 67 rear with a casting # NF 3917124. I cannot tell if the date is C,D or E, 10 7. The numbers on the axle are F O or Q 5 17 B and there is an E under the 5.
The posi carrier has EDB30174 which is a 4 series posi. The ring gear has 80 7077 1 * 1<>78620 it has 39 teeth and it is supposed to be a 4:33. I posted some pic’s to help. Thanks for any help

I read the axle code to be

F 0517 B

0517 being the date code MMDD

05 - May
17 - Day
B - Buffalo NY axle plant

E - Posi carrier mfg

There should be another letter in front of the F but I can't see it, no 1967 rears started with F.

you have a choice of
CF
KF

Looks faint, but is that a C over on the left of the F?

Thanks for the help, anybody have anything on the ring gear?
