Hi,
You should have four each of the collared rubber bushes and two each of the smaller bush.
The rubber bushes go either side of the tongue (x2) on the main mounting bracket and the small bush thru the rubber bush. Flat washers on either sides of the rubber bushes so that you have a rubber cushioned mount.
The bigger bush between the rear of the alternator and the rear tongue to keep the alternator from moving back and forth. If there is more room, add flat washers to make a snug fit.
For the adjusting rod, you need a special bolt with a collared shank so that it would not flop about when fitted.
I believe this is not the original alternator for the car, but it can work.
Hope this helps.
New rubber bushes weere available when I did this job (2002?)
Hope this helps.
