Yeah, I was thinking about that, but due to the design of my frame rails and rearmost crossmember, I'm going to go with a custom plate that I'll make out of 3/16" plate. I probably won't go under the entire tank. I'll probably go under it until when looking at it sideways, it will hit the rearmost edge of the tire. I doubt I'll ever hit it closer to the front from there.
