Stabilize your dash and restore structural integrity on your classic 1973-1991 Chevy or GMC Squarebody truck or SUV with AMD’s premium Dash Frame to Firewall Brace with Hardware. Precision-engineered to match GM’s original design (GM part# 371589), this brace is crucial for strengthening the dash frame, reducing flex, and improving overall cab rigidity.
Also compatible with early 1973-1974 dash frames for seamless retrofitting.
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.
This dash brace bolts directly to factory mounting points using the included hardware kit. It’s a perfect bolt-on fit for 1975-91 models and retrofits easily into early 73-74 dash frames. Installation requires minimal effort—align, bolt in place, and restore that factory-sturdy feel.
Eliminate dash shake, reinforce cab rigidity, and give your 1973-91 Chevy or GMC truck the support it was designed for. AMD’s Dash Frame to Firewall Brace with Hardware is the OE-correct solution your Squarebody build deserves.

Auto Metal Direct is a team of true car guys with years of experience in sheet metal reproduction, car restoration and paint/body work. We believe that quality is not subjective! Our mission is to provide the best customer experience for the Ford, Mopar and GM classic car markets - both in products and in service.
Our panels are made from proper gauge steel and include all correct-as-original clips, tabs, flanges, bends and seams. Each time a prototype body panel comes off of a new tooling, we test fit it on a car. The marked up prototype is then used to change and improve the tools, and a new prototype is produced. This procedure might be repeated multiple times but, once the part is finally approved, you can be assured of a quality part.
