I am no expert but I think this is correct CW = 3:31 Ratio 7 = 1967 12 = December 9 = 9th day b = Buffalo Plant

So that might be a for a `68 car then no?

Thanks

The year is not shown in the stamp. You must have misread the 7.
(MM/DD)
The year is shown in the center section casting date. Small raised
code on one of the axle support gussets. Look facing the cover opening at the 5 or 7 O'clock position.
Letter for month and numbers for day and last digit of year. Looks similar to this:

Ok,i`ll get the casting #s off the housing,the rear is suppost to be a `67 rear i just wanna make sure its not 68-72 rear,i bought one a few years back with the 7 casted where you show in the pic and it turned out it was the wider 68-72 rear.

Thanks

Just to be clear the year shown in the casting date is the year cast , not model year...For '67 model year only those cast Jan+ '67 will show a 7.

Thank you very much for the info and help.

Thanks
