I had the problem of not having the right pulleys. for my 8 bolt water pump. the engine I bought had a 69 balancer with 8" 3 groove pulley. the water pump pulley was a 6", 2 3/8 deep. I originally put a 7/8 spacer behind the pulley to bring it out, but then the mechanical seal went out on the water pump. I thought here was my chance I went and bought a 11 bolt timing cover and water pump. Installed it everything going great until I went to put the water pump pulley on.

NOW it's off by a 1/2 the other way (not deep enough). The water pump is just shy of 4 1/2".

Does anyone know what I need for a pulley? the one I have is 481040XT.
