Pontiac did not use a Powerglide transmission, ever. Neither did Buick or Oldsmobile.
They did use a planetary two- speed known as the Super Turbine 300 ,or the Jetaway, depending on the brand. The only thing that's the same as a PG, is the gear ratio (1.76 PG) . The BOP trans is a stronger unit than the PG in stock form, but it never had any aftermarket support.
Calling one of these 2- speed transmissions a Powerglide would be no more correct than calling it a Fordomatic or a Powerflite.
Now , for your question. Put a Turbo 200 3 speed in it and look for a Chevelle , Monte Carlo or 70 GTO 12 bolt in it in case you ever want to use a 4.33 ring and pinion.

68-72 12 bolt chevelle/70-72 monte carlo rears will be a bolt-in (bring checkbook)
64-67 chevelles are an 1.5" narrower(bring 2 checkbooks)...
if you are not going class racing,i'd stick a 9" in it.
it'll be cheaper in the long run...
