You should be able to sell these pieces for a lot
once they're out. Here's a link for this stuff new: https://www.metalsdepot.com/steel-pr...el-floor-plate
. Your stuff would be well over $100 new, could probably get at least $75 a sheet on CL or Facebook Marketplace.
If you're 5'11" in a 6' bus, you're definitely going to want all the headroom you can muster.
