Im getting ready to do an engine swap and I need to know if the stock TH-400 is a BOP (Buick Olds Ponti) so I can order the trans adapter.

Nope, the stock Jeepster Commando TH400s were an oddball Buick Olds Cadillac bolt pattern that was used in some 60s cars. If you look at the front of the stock tranny you will see a factory adapter ring that adapts the TH400 to either the Buick or the AMC engine depending on what year you have. What engine are you swapping in, SBC?, it might be easier to use a GM bolt pattern TH400 instead?
