Im off work for a few weeks and I dont keep this size at home...32 will be fine but loose. if your gonna go this way you may as well take a shifter it will be tighter! 45 mm depth is fine...tip to hex base is 38mm. Have you got a map gas blow torch? just heat it off. Ive got brass shim if you want it or worse case ill take a nut off one of my mowers and you can get me one later as it aint going anywhere, and this is all sounding too hard as ive never seen so much attention paid to NUTS baahaaaa! Na im just clownin if you need anything I suggested come grab it....and bring me a choc chip muffin, im starvin
