This firewall was inspired by our smoothie Trifive firewalls but redisigned for the Advance Design Chevy and GMC pickups from 47-55 first series. It features a 2" recess that works great with any engine.  Recess is 25-1/4" x 23-1/2" x 2".  It really helps to clean up that engine compartment in your truck. Fabricated from 16ga steel by Hot Rod Dynamics. Requires basic fabrication and welding skills.
This firewall works with the RainGear wiper systems and Vintage Air Sure fit or GEN IV Magnum evaporator kits
