Thanks to Rusty, I found this alternator that seems to be the same as is
supplied by Vans for their kits.

Lester number of the Vans alternator is 14684. This is a ND internal
regulator, internal fan, 55 Amp, 12V, Clockwise, 1 Groove Pulley
alternator used on 87-88 Chevy Sprint, 86-95 Suzuki Samurai, and 89
Suzuki Sidekick.
It replaces the ND 100211-141, 100211-155, & 100211-407.

I will have to replace the 1 groove pulley with a 4 groove and it should
bolt up to the Renesis.
I had originally planned to mount the alternator in the stock position
but leaned over to the passenger side, however I found a bracket by
Pineapple Racing ($69) that will mount the alternator down on the side
(passenger) and this will clear the area where the Renesis normally
mounts the coils, which would allow a stock mount of the coils.

Thanks to everyone who replied.
If anyone knows how, this info could be placed in Wiki..?
