One wire alternator for race car

Hi All,

I'm looking for as simple as possible alternator for my '73 240z race car. I know Motorsport Auto (The Z Store) has one at a reasonable price, (Motorsport! SALE! 60-Amp Alternator Upgrade Kit, 70-73 240Z - The Z Store! Nissan-Datsun 240Z-260Z-280Z-280ZX-300ZX(Z31/Z32)-350Z-370Z Parts) which I will order it this week if I can't find another, but I'm hoping I can pick one up locally and install it right away.

Anyone know what model Bosch it is that they use? Or, one that I can just bolt in with the same brackets and use one wire to the batter?

Thanks

Bill Oakes
