[ndamood]

I need to find a big enough piece of sheet metal to redo the bed of my new/used,(new to me but used) k-5 blazer (the one that jbk5) was selling. L.O.R........... "Lot's Of Rust" the rest of the sheet metal is no problem just the bed is what I need, & I know that tey sell it in sections for the c-10 16"x48" but I did not want to have that many weld mark across the floor, that's more work to please help,is there any sites for sheet metal this large? help & will send pictures of progress. thank you.
