I have a 1937 Chevy 1/2 ton pickup that has sheet metal welded to the bottom of each seat. Since it was done so poorly, I have to believe that it was an attempt to keep out the mice and bees, rather than an attempt to fix an actual problem.

I also found small pieces of window screen stuff into each open hole in the cab. Again, I'm assuming he didn't like bees in his truck.

Should the underside of the seat be open normally? Or should there be some sort of metal pan on the seat base?

Thanks for your time.
