50 cal, my seat belt mounts and mounting it to the cage/seat frame determined the odd cut pattern. If you have the room you might not need cut a 50cal down. Insides just spray can bedliner.
Approximately what were the dimensions of that can before you whacked on it? My 50 Cal looks a lot smaller than yours. There are about a dozen different sizes looking at those for sale on the various web sites. Not sure I have the right size.
