I checked all the yards around here and wasn't able to turn one up, so I bought one of eBay and I have it in hand. Here's the problem - when I try to put it on, there is a ridge on the water pump that keeps the bracket holes from seating all the way against the mounting holes on the water pump and the head.
Here are some pictures that show what I'm talking about.

So the question is - can someone confirm that there are spacers that are supposed to be installed behind the two water pump mounting points? Is there also a spacer that should be installed at the head mounting point? Does anyone have the size of the spacer?
Thanks guys!
