It does have a serpentine belt, so I am going to give this solution a try.

This is actually the second alternator swap I'm doing on this car. I swapped out the original 65 amp alternator for a 120 amp Volvo alternator when the stock amp couldn't handle my stereo amplifiers. This required the shop (the car is in Peru) to modify the mouting bracket and install a slightly longer belt. I've never been happy with the modification, as the pulley is not perfectly true and in line with the rest of the pulleys and wheels that the belt winds around. This causes a lot of stress on the belt tensioner -- which I have had to replace twice after it snapped off the mounting bracket.

I'm going to ditch the Volvo amp, replace the modified alternator bracket with a new stock bracket, and install the 143 amp alternator.
