Direct Sheetmetal firewall with 4" setback fits the 55-57 Chevy. Custom setbacks are available. Please specify custom setback in comments section of your order.
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.
