Looking for an opinion on gaining a little more clearance on the fan blades and the nut on the power steering pump. I had the power steering bracket off while installing a new intake and carb. Once I put it back on and had it lined up right, it seems as though I lost a bit of space, or maybe it was always a little close. Not sure.. My thoughts were, grind all 4 blades down evenly or put a spacer behind the fan. How much clearance would be regarded as safe?
