Product Description

Dynacorn Firewall Assembly In Weld-Thru Primer for 1965-1966 Coupe and Fastback Mustangs.

This is a complete firewall panel for 1965-1966 Coupe and Fastback Mustangs, which includes the entire vertical panel up to the cowl and the two toe board panels that attach to the floor boards. Dynacorn's premium-quality OEM-style replacement firewall features heavy gauge stamped steel construction with a weld-thru primer finish for additonal rust protection. An original 1965-1966 Coupe and Fastback firewall had a flange on the sides where it meets the A pillar. Our replacement firewalls do not have this flange so you will be required to fabricate it. However, installing torque boxes (recommended) will fill the gap and you can simply seam seal the space instead of fabricating a flange.

Advantages of Weld-Thru Primer:
- Reduces prep time when welding new parts to new parts that are both covered in the weld thru primer
- Reduced spatter
- Lower distortion of the panels
- Superior conductive properties that help minimize high heat zone problems
- Eliminates corrosion that would form between overlapped panels or multi-layered spot welds
- Helps when welding a new panel to old metal
- Lower resistance at the weld surface allows better penetration into the denser, new steel that helps forgive an old alloy's problems with porosity and impurities
- Helps prevent resin build up between welds that can trap moisture in the old porous steel that leads to failure at the weld borders

*Requires modifications to fit convertibles.

Dynacorn Firewall Assembly In Weld-Thru Primer Coupe/Fastback 1965-1966 is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Awful Stamping I purchased this product and have since arranged to send it back. It is an awful stamping, even by repop standards! There are SIGNIFICANT waves, wrinkles, and folds in the metal throughout the piece. I contacted CJ hoping this was just a bad piece. They checked the other Dynacorn firewalls they had in stock and they all look like this!
