Switch or cover plate in dash hole for dual tanks?

[Nick_R_23]

I removed the dual tank setup from my truck including the lines, wiring, and selector switch mounted on the dash. I'd rather not leave an ugly, open hole in the dash where the switch used to be, and I'd also like to not have a useless switch hang out in there either. Were there any other switches made that fit this hole that may be a little more useful? Or better yet, does anyone make a blank plastic cover to just fill the hole?
