It depends on when the PG was made. If it's an early model with a cast-iron case, it might be a difficult swap. The later-model with the aluminum case would probably bolt right up, especially if it was originally installed behind a V-8 engine. The PG is a 2-speed transmission, with two basic ratios, too low, and too high!
The 194, 230, 250, and 292 engines have the same bellhousing bolt pattern as the Chevy V-8, so if your Powerglide was installed behind one of these sixes, or an 8-cylinder engine, it should bolt onto the engine with no problem. If it was behind a 235 engine originally, the bellhousing bolt pattern will be wrong. BTW, the aluminum PG is in great demand by round track racers and drag racers, so an ad on eBay might get you enough cash to get a complete new clutch, pressure plate, throwout bearing, and flywheel refacing, plus labor, with enough cash left over for a 6-pack or two! Check out the PG prices in the JEGS catalog, or from TCI (Torque Converters Incorporated).
