waterpump pulley?

It looks like that is the incorrect water pump pulley. There should be no spacer between the water pump, and the pulley. It should be in line with the crank damper. The is a two shiev alternator pulley, but it is not needed. In your picture the belt should be in the groove closest to the engine on the crank.
Looks like the wrong pump pulley to me too. 3/8" pipe nipples can be cut to length for spacers ,
I u need to go that route.
