Direct Sheetmetal firewalls are made out of 16-gauge (.060 in.) cold-rolled steel and are available in a choice of setbacks to accommodate engine swaps. They are hand-formed in DSM's shop and, like all Direct Sheetmetal parts, are designed so the average hot rod enthusiast can install them in their own garage or workshop. You do not have to use a new floorboard if you change your firewall, but all DSM firewalls have a floorboard to match up to. This often makes for a more professional installation.

Although DSM firewalls do not normally have to be trimmed, some may because every car is different. Direct Sheetmeta
Direct Sheetmetal firewalls are made out of 16-gauge (.060 in.) cold-rolled steel and are available in a choice of setbacks to accommodate engine swaps.

Although DSM firewalls do not normally have to be trimmed, some may because every car is different. Direct Sheetmetal makes their firewalls to overlay other parts so trimming is OK. Bigger is better--it is harder to add material than to trim material.
