      Comments about Proform 100% New, Chrome Alternator, Gm 1973-86, Internal Regulator:

      Could not mount the alternator on my car. This is a custom installation (V8 small block Chev motor in a 37 Chevy body). The unit I was trying to replace is longer from the mounting bracket hole to the adjustment bolt hole. Since I could not install it, I could not test it. It is probably a fine product.

      • Q:

        I have a 1966 Impala with a 350c.i. motor. Does this alternator have the same dimensions as the externally regulated alternator I have in the car now? I am upgrading the wiring and I need to change to an internally regulated. I just want to be sure the pulleys/brackets I have will still work.
