I ended up buying a universal alumi crank pully from Mancini,s so my waterpump and cranks pullys would line up on the 410.I tried one of the flexolite adapters,but it was to thick.Just mentioning what I had to do.:D
I already had about 1/4" of spacers behind the water pump pulley and the Crank Trigger I am using is 1/4" Thick. So what I am doing is taking out the 1/4" Spacer behind the water pump pulley and setting the new 1/2" spacer in there which will make it line up with the lower pulley that will have the 1/4" thick 36-1 Trigger Wheel behind it.
