Why This Brace Matters:
Over time, it’s common to find the original dash-to-firewall brace rusted out, missing, or damaged—especially where it meets the firewall. GM added this brace starting in 1975 to increase dash stability and reduce structural flex. AMD’s reproduction brace offers a factory-correct solution, essential for anyone restoring or reinforcing their truck’s cab.
Whether you're completing a restoration, tackling rust repair, or assembling a new cab as part of AMD’s Build Your Own Cab Program, this brace ties your dash frame securely to the firewall, delivering long-term strength and stability.
