[FC] Greenbrier 64 differential

[Rad Davis]

Bob's wrong on this one.  '64 GBs (and presumably the few '64 Rampsides 
as well) have the boss on the bottom of the diff case for the leaf 
spring.  I know - I have the original trans and diff from a '64 
Greenbrier in my '65.

The '65 Greenbriers probably came with some '64 diff cases and some '65 
diff cases, but we know that there were '65 cases made with the control 
arm mounting pads cast on the bottom and a speedometer drive installed 
in the side as with an early case.  Tim Schwartz in NJ has an NOS one if 
you want to see it.

In short, When GM needed more FC diffs, they built them out of whatever 
case was coming off the casting line that day.
