Overheating issue with March Performance pulleys

quick question, did you have any problems with the center register on the march water pump pulley fitting on the water pump snout register? I got a set of these pulleys and the register is 3/4" on the march pulley! way too big! it just wobbles around and ya cant locate it properly.

I didn't have any problem, fit good and tight. It's been forever since I measured one but I think it's 5/8". I'd call March and ask them. sounds like they either gave you the wrong pulley or machined it out too big.
