[Vwdiesel] alternator adjustment strap

[Doug & Pam]

On one of the Caddy's, I have the two eared alternator with the adjusting
strap under the alternator. It is difficult to get to because it also has
power steering and the hoses are in the way as well as the water pump
bracket. I lost the pivot bolt from the adjusting strap and the alternator
dropped down out of position. When I disassembled it to correct the problem,
I found that the adjusting strap seems to have a bushing at the pivot bolt.
Before losing the pivot bolt, the bolt beat an egg shaped hole in the
bushing. What is this bushing made from? Can they be replaced? Can they be
substituted?
