Direct Sheetmetal front floor kits are made from 16 and 18 gauge steel. All are hand-formed in their shop right here in the USA! 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 achieve the best fit. This kit fits the STOCK firewall.
