MiraclePieCo,

Another option I should mention that applies to the Task Force trucks but I’m not sure if it was ever available for the Advance Design trucks (DOesn’t mean you couldn’t develop one for yourself):

Somebody used to make a Fiberglas firewall cover that bolts OVER the firewall and fit under the pinch weld along the top of the firewall. It was mounted using the four hood hinge bolts on the ‘55.2-‘57’s. I know because I knew a guy that used one for his and you couldn’t tell it wasn’t the stock firewall unless you were looking for it. I looked awhile ago for myself (trying to think of the aftermarket company....it’s out here in California, I want to say in Riverside or San Bernardino) and they were no longer selling it.

EDIT:
It’s No Limit Engineering and apparently has moved to someplace called Dandridge, TN
