Direct Sheetmetal kits are made from 16 and 18 gauge, cold-rolled steel, and are all 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. Every car or truck is different, so slight trimming and re-shaping of some parts may be necessary to achieve the best fit. Pieces may be purchased separately.
