I agree that the smartest thing is probably to to go back to the original alternator, but I am having a hard time fnding the same size with an external regulator (Any ideas on where to find a 55amp external regulator alternator?) Also, I woud like to upgrade to a 70amp model. There are several previous posts from people that have had success with the fan housing modification. How risky is the modifiction to the housing? I'm not a machine shop expert, but I would think that a good shop could maintain the same angle in the housing.
