Brief Description: Rivet the Firewall Assembly Together
Step 4: Rivet the Firewall Assembly Together
Now, use 1/8" monel universal-head rivets [165] to rivet the firewall flanges to the front of the firewall sheet. When riveting on the flanges, be careful to preserve their relationship so that you maintain the shingle effect described in the last step.
Standard riveting practice would have you install the rivet head on the tab side of the firewall flange. From a practical standpoint, it will be easier to wipe down the engine/firewall compartment if the rivet heads are on the forward side of the firewall.
