I paid my mechanic to install my FMS pulleys because I didn't have access to any air tools. They didn't have to take anything out for clearance but they did have a hard time with the alternator. The bolt was cross-threaded or something so it gave them some fits. I'm glad I didn't mess with it. They charged me less than $60 and it took them two hours to install. Seemed like a pretty fair deal to me and the results were about what I expected with no overheating or poor charging.
