Completed the shake-down runs with the alternator conversion, and I really like the results. All of the lights appear brighter at night, and no dimming during stop lights idling. It mounts with only one mod on my '74, I had to grind down the bottom sliding bracket to clear the fans on the pully. I could have used the old pulley, but the new one looked much better. Lifetime warranty also. I used the instructions from Skye's reference pages. I believe done by Bob Munchausen (spelling?). A buddy of mine did the GM conversion, using the instructions from the Teglerizer site..good stuff.
