I think all the frames are the same- just have to swap the pulley.

There are lots of ppl running the 110-143 amp and the 150 amp models.. on v-belt cars(up to 2001Alternators).
Used they are $50-125. Most ppl throw a new regulator/brush pack on the alt which is another $30-35. You can do bearings too for another $20. Rears seem to get a bit noisy- and it's the cheaper brg.

You have to make a new harness for the wiring- need switched power source and then bigger cable to take the power.
