I would think if you had the right water pump pulley that you could run a belt over one of the crank grooves/over the pump pulley and one of the alt pulley grooves. Me I would undo some items & see what you need to do to get things to line up. I may have a pump pulley if you have the dimention of what you need. there are spacers to move the crank and pump pulleys further forward and even with the 2 alt pulley grooves you can space the alt out quite a bit & in further a little bit.
