Ron, as you switch from brand to brand most companies vary the size of the plate slightly in an effort to keep you buying their products. Compare the sizes of the plates and lift plates before making your purchase so you know which to go with. You can make a plug and glue it into a plate opening and then rout a new opening. Depending on the exact situation you can often just install the new plate size and live with some slight openings on two sides of the plate.
