The AL69X is another alternator often swapped in, its rated at 80 A.
Anyone contemplating a swap needs to be concerned with the pulley, its possible you will need to swap that too, and the connectors (wiring harness).
Most high current alternators use a bolt for the output and for the field connection, the stock alternators used a plug that fits onto the alternator, obviously you need to connect differently and having some electrical knowledge will be helpful.
Here's a short thread on the 126 subject:
