Hello, I need to replace my alternator this upcoming weekend, however when I installed Sr performance UDPs a while back, I had to shave off part of the stud supporting the alternator in order to get the pulleys to fit. Now that I need to swap out my alternator, I’m worried I’m not going to get the nut off the stud because of when I cut the end off with my angel grinder. Any suggestions on how to get the nut off?
