not sure here , but 65  4 spd with  a 63 differential?  splines the same? I 
thought there was a change in 64? I have not done much on  std shifts in a 
while , but one time there was a difference in splines that did  not show up 
until the car was on the ground..under load. At that point there was  noise 
without motion. BUT I thought it was 63 transmission against a  later  
(64-65)  differential..I could be wrong again .
The powerglide leak : usually the converter seal fails , doing a full  
dump, then you put it all together without doing the internals and the  inner 
one fails putting trans fluid in the differential until it comes out the  vent 
on top big time. I have seen this more than once lately. I think I posted  
pictures of cause and repairs a few years ago on a web site. I just would 
not do  any differentials anymore without doing that internal seal. 
I made a tool that gets that seal out without disturbing the bearing  race.
For some reason these failures are hard to understand , unless you have had 
 it happen and done the job.
