Was going to do this, but it suggests that it only applies to the 11 bolt pumps. Thought all 1st gen pumps were 8 bolt? Mine is, so I guess I can't do this mod on mine.
It is a bit more complicated on a 8 bolt pump but still should be done. Problem is the rear plate on the 8 bolt is fitted inside the timing cover. I lay both plates on the water pump and just get the impeller to touch the plate. Also make a few bends in the outer edge of the plate so it gets sandwiched in between the water pump and timing cover and doesn't move around. With the water pump gasket installed you have proper clearance.
