Alternator Adjustment Bracket
Description
If you use the GM 1-wire alternator setup mounted below the fan, you
need a method to tighten the belt.
While I was expermenting with different solutions, I found a
generator adjustment bracket off an old tractor and decided to try it.
After one bend and one twist I had found the solution I liked. The
entire alternator installation is self contained to the engine and
looks like it might have come that way.

milling out the slot.

- Using the Cutoff Disk in the Angle Grinder, cut out the remaining
material between the 5 3/8" holes to create the slot.
