For all intents and purposes, the function of the two gearboxes is 
the same.   However:

The 2nd generation 4-speeds were stronger, so as to accommodate the 
larger displacement engine.    If you  don't flail the car like a 
teenager who stole it, the earlier gearbox should work out fine.

Somebody correct me on this if necessary...   but I believe that the 
quick way to ID a 2nd gen ('64-'65) 4-speed gearbox is through the 
lack of a drain plug.   '61-'63 gearboxes have drain plugs.     At 
least I *think* the drain plug was deleted in '64 with  the 
introduction of the beefier version of this gearbox; the '65 variant 
for sure has no drain plug.  Of course in '66 the Vair-specific 
6-bolt Saginaw gearbox came along.

Again, somebody correct me if I'm wrong about the '64-up drain plug.


One never knows what's what anymore; a friend has a '63 Spyder that 
has a '61 vintage transaxle in it according to the numbers stamped on 
the diff pad.
