Well, the old 17ACR died on my sister's '70 BGT (on a dark night in the rain, as usual!), so I've replaced it with a Ford Fiesta unit (55Amps), which should be enough to cope with her high powered stereo (no other major accessories or loads).
I upgraded to an 85 Amp Bosch unit in my '70 GT, but it required a little more fiddling and engineering to mount, whereas the Fiesta really is a straight bolt on. Sadly the much ballyhooed Saturn unit is not available ANYWHERE in the world but the US (and shipping to NZ makes it too expensive). Having said that, I'm very, very happy with my Bosch unit (BXF1255A), and can also recommened it to anyone.
Thanks to Bob Muenchausen for his well read tips on the Fiesta upgrade. My experience:
1) Straight bolt on. Just had to move the internal spacer piece in the back alternator lug a little
2) Had to trim a little off the original lower mounting bracket, as the slightly larger fan of the Fiesta unit just caught it.
3) The Fiesta unit is a nudge 'fatter' - so needs to be lifted/rotated clear of the engine mounting point. This requires a slightly longer fan belt - an extra ~30cms over the stock 900mm.
4) The wiring was very straight forward: the old lugs slipped out of the original plastic sleeves and clipped right on. Also added an extra 10ga brown up from the starter solenoid, just to ensure maximum output availability.
