Direct Sheetmetal 67-75 Chevy Truck Firewall features a 5" setback.
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.
(possible extra charge for shipping).
