There is no disagreement with Mike and others,most all suggestions are viable.As for us we like to apply the KISS method to save time and money that can be well spent on other more important areas of engine assembly.Anyone can shave down the sides with minimum effort with a belt sander or mill or other means.Just shave the bottom edge straight and don't fuss with the top of the angle.These plates are not accurately cut to begin with.We see some that all we had to do was shave a little off each corner.
