Like I said, I did have to trim down the loop that goes over the top of the trans where the trans cross member is, but other than that no cutting.
The driveshaft was cut down for the difference since the A500 is longer. (about 4 inches shorter)
That is Great information to know as I embark in what will be the best (Read: Least amount of cutting on the car) combination of Newer Generation Powerplants/Transmissions into my Swinger. Sounds like the A500 is currently leading the pack on the way to proceed.
