Use this kit to repair your rusty floor for a super clean installation. Direct Sheetmetal kits are made from 16 and 18 gauge, cold-rolled steel, and are all hand-formed in their shop. Each part has been designed so that the average hot rod enthusiast will be able to install it in his/her own garage or workshop. Each kit contains mounting hardware and an easy-to-understand instruction sheet. NOTE: Every car or truck is different, so slight trimming and re-shaping of some parts may be necessary to get a correct fit.
