Personally, my problem with cutting down the water pump nose is reassemblig the thing. Water pumps usually use a pair of sliding discs known as a 'carbon seal' and getting them back in, with a proper press fit, without cracking them or leaving too much clearance, I've been unsuccessful. FWIW, the seals are sort of like old VW bug throwout bearings but thinner. Maybe I need instruction?
