69 fan spacer bolt question

I have the correct water pump, and pulley, the 2.5 inch spacer (535253) and correct balde ( 9791346) but the spacer bottoms out on the pump snout before its on far enough to seat the pulley against the pump snout? What am I missing here? It appears that the snout isn't going into the spacer far enough? Thanks

The bore of the spacer has what looks like a sleeve about 1/4 of an inch in from the end of the side that slides over the water pump snout that's preventing it from going on far enough to seat fully

My mistake. I thought it was a sleeve but it looks like it was not bored deep enough to the correct I.D. it only needs to be about .080 deeper to fit properly

Here is a picture of the water pump. It's a new version of the " short style" that Ames sells for the early 69 models.

x2, seems way to long on the stick-out. Shorten with a die grinder/cut-off wheel and polish up with a grinder. If you drill the spacer, you may oversize the hole or even offset drill it - unless you can chuck it all up on a drill press. You don't want any vibrations as the pin/hole should be tight.
