I already have the wiring schematic for the alternator, but what I dont know is what year and model Datsun/Nissan to snag an alternator from.

What do you want to do? Upgrade your internally regulated alternator?

If you have an older 510, you can upgrade to a 50amp external regulated alternator. 1977 200SX.
Or if you want the small size 60amp internally regulated alternator, get the 1978 200SX Bosch rebuild. Bosch makes a 50amp and 60amp rebuild for that year. If you've got room for the really big alternator, which I think the 510 does, then get any year 280ZX alternator. 60amp, IR. 79-83.
Datsun 521 and 620s with an L16 or L18 must use the smaller size. The idler arm won't fit a ZX alt. I'm using the 78 200SX 60amp in my truck with an L18. It bolts right in, and uses the 78 200SX alt belt.
