In my mind the only way to correct it 100% is to include the plates with the pump.

Like you say, I've said right along that the plates need to be included with the pumps. But if Ames is willing and can correct their plate that will work, then they wouldn't need to be included. Their plate as it is now only works with impellers that have been shaved down and the original correct impeller contour is lost.

I also believe the keyway will need to be cut into the SS plate too... just like the originals where. The keyway locks it in and the hump in the timing cover becomes a part of the plate.... all due to the curve of the plate and the impeller's contour. No keyway and the impeller will hit the plate. I've proven that truing to get this new pump installed using both plates. Original works, SS plate won't.... as it is from Ames it hits the impeller.

Here is the correct impeller contour and set so it's correct to install.....



Here's the original divider plate's contour....



SS Plate contour showing where the impeller is hitting the plate....



And the side view of the SS plate showing the contour and then it being flat to the center....



These are the best photos I could get for the SS plate. Maybe someone with a better camera than mine can get better shots and post them showing it's contour.
