[6pack] Early TR6 Trans into a 64 TR4

Will a 1970 TR6 4 speed trans swap into a 1964 TR4.
I'm in the process of adapting an A-type O/D to a Trans and have lots of 
spare 4 speeds around and thought it would be easier to mate up the 2 
(trans and O/D) for a quick swap later.
The only big difference I have seen is the rear companion flange is 
different than a TR6 but the O/D has a TR4 Flange.
Thanks in advance
Glenn
