Installed an 80AmpBosch AL124X alternator from a '90 Saab 900S in the '85SD.

The alternator works great except that I get a bestial squeal from the alt belt ever time when first driving off for about almost a mile. The belts are tight so I'm wondering if the Saab's pulleys (which I kept on) might be slightly different from those on the original alt and that that's causing it. Any suggestions?
