Hey guys - I have a March pulley kit for my BB and the bolt heads (that secure the water pump to the pump housing) are too big. The inside rim of the pulley is making contact with the bolt heads. The water pump is 440 source I think, if that matters. I seem to recall there are water pump bolt kits with short heads to solve this problem. Can anyone point me in the right direction on where to buy them? I called March and they thought I was nuts. Thanks in advance!
