5. You can skip the next few steps for the 95-amp alternator, but for the small amount of extra work we really suggest the 130-amp unit. There is a small amount of grinding to the bracket required, which can be done on the car if you like, but we removed the bracket to keep aluminum shavings away from the engine compartment. The bracket is retained by a 9⁄16-inch bolt, shown here, and two �-inch bolts on the opposite side of the vertical support. You will also have to remove the Thermactor air pump mounting bolt (but not the pump itself) if your Fox still has the pump installed. This ’89 clearly did not, as you can see by our lead photo.
