The Stovebolt Forums Forums The Shop Area Interiors padded firewall cover

I bought one of the padded rubber faced firewall covers, to replace the original cardboard one. It had precut knockouts for mounting points, grommets, etc. If I line up the grommet holes, then most, at least half of the mounting holes don't line up at all. I'm going to have to drill some new holes in the firewall, or in the cover, in order to get this installed. My only question is, is this normal? I was a bit surprised, although I guess I shouldnt be, as this seems to be pretty normal with most reproduction parts. Why is it that every 20 minute job on this truck ends up taking 2 days?

I bought a hard faced (PCV) cover, and ran into the same issue. I modified the cover rather than the firewall. For the most part, it’s covered by the dash so you can't see the modifications.

I would think that the factory firewalls would be pretty uniform in production, so the fault lies in the aftermarket imports we get. I find most import parts I have to modify to fit so your not the only “bolter in that boat!
