Are you talking about height or width of the cap. I trimmed the ends some to get it to sit down on the side plate! I left it tall because we may go to a 22 at some point. I really don't think it is much over notched anyway. We also drilled a hole and welded a nut on the inside of the bottom cap to be able to run a bump stop! When you dump it its about 3 inches from the notch and we are just now raising the tank. As far as width of the top plate I would let it over hang the side about 1/4 inch to give you something to weld to. I didn't do that on the top plate but did on the bottom.

Hope this helps let me know if I can help on anything else.
