Ok so I figured out what the problem was. The adjuster bolt is actually seized in the pinch block. This is why I couldn’t lower the alternator enough. I ended up completely removing the lock bolt to get the alternator out, so I could get a look at it. Right now I have the car running with the alternator held in place only by the top mounting bolt being tight, hehe. I need to get a new pinch bolt, adjuster bolt, and pinch block, now…
