Direct Sheetmetals 35-36 Chevy Firewall is available with a 2" setback for the small block or a 4" setback for a big block.
Direct Sheetmetal kits are made from 16 and 18 gauge, cold-rolled steel and are all hand-formed in their shop.
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 get a correct fit.
