Tunnel cover

[Aguinaga]

Has anyone bolted down the tunnel cover vs rivets? I like the idea of being able to remove it if need be.

I used rivnuts, and bolts. A lot of builders have made it removable. Some used sheet metal screws.

Thank you for your insight.

I used self-tapping sheet metal screws, then replaced them with shorter hex headed sheet metal screws. Rivnuts are probably the proper way to go, but I had self tappers on hand lol

I’m strongly considering rivnuts for our tunnel cover and some thing for the firewall. I’d like both of these to be removable

I just tapped the tunnel directly and secured the cap with M4 machine screws

Welded coupling nuts inside the tunnel and bolted through the top vertically.
Along with additional bracing and bolting at the shifter mount.

Yep. Just tack screws here.

I wanted to use rivnuts in place of the rivets but the holes in the tunnel were so close to the top of the steel I was worried that by drilling to a larger size the edge would tear out. I have used M5 rivnuts for all of the floor pans and rear firewall though. Perhaps smaller rivnuts would work better to hold the tunnel pieces down.

I used black zip ties and drilled the cover. 3 per side and 4 up top. Used 3/4" soft black foam weather stripping and everything seals up nicely. My cover did not fit perfectly. The foam helped fill the gaps. I also painted the underside of the cover a matte black. Everything blends nicely. I also used a soft pipe insulation between the cover and the hood to direct the warm air to the sides. Where the pipe insulation was crushing too much, I put a piece of leftover rubber hose inside - zipped tied that down too. Works like a charm... Whatever you use - only you will see it. The hood is not easily removed so you won't be showing it off much.

DUH... Sorry

I drilled and tapped. My problem is I would have to remove my side covers and wide seats to get to the tunnel cover. Its fairly permanent however you do it...

I think he is asking about the tunnel cover not the footwell cover.
