I am getting ready to install a 1/8 aluminum sheet on my firewall. I like the looks of the satin finished aluminum and it will give the truck an old hotrod appearance.

Question is what do I attach it with, I have thought of rivets every 4 to 6 inches apart. Maybe some selftapping sheetmetal screws. Button head allen....either black or polished stainless. I have even thought of using some 1/4 turn quick fasteners. Maybe some sort of epoxy and leave it clean with no noticable fasteners.

The truck in question is my 1941 Chevy pickup. It has Moon discs on all four corners and all satin aluminum engine components (handmade Olds style air cleaner and old M/T fined valve covers).I/m getting readt to do an aluminum dash insert also in satin.

What do you guys think...how to attach it. Maybe I havent thought of all the options.

Input would be greatly appreciated

I made a 1/8" firewall for a '68 Nova, fastened at equal distances with small stainless machine screws, through upholstery style grommets, passing to the interior side. When attaching it, remember that any place the aluminum isn't fastened, if touching or near the old firewall (if you didn't cut it out) will cause harmonics and vibration that will make you crazy trying to locate.

HI,i put a 1/8 inch aluminum firewall in my 23 T roadster,i used double sided tape to hold to firewall, my throttle cable bolted thru the aluminum helping to hold it in place.,worked great.

Are you talking of stuff like 3M body moulding tape? I never thought of tape, thats why I put the post up, lots of good ideas. Even if I do use other methods to fasten the aluminum, the tape might help with the issues of rattles and harmonics that Larry was talking about. By the way, the original firewall is still in, mostly, the previous owner hacked a pretty big hole through to install the steering column. I know I'm going to have to do something about the raised stiffening beads on the firewall but I'm not too worried about that issue. ( heat and hammer I think)

Keep the thoughts coming guys, I'm still a couple days away from installing

i did mine with steel, 16 ga... i used liquid nails. 1 tube did the trick and it is stuck very solid

I'm designing stand off bolts to flush mine out with the cowl flange. The space between I'm going to use to hide wires etc. The surface will have a nickle plated acorn style nut.

If it is just for looks I think the epoxy would be the hot set up. Make sure you have a good close fit, and free from road grime and have at it. Maybe some 3m tape to hold it in position while the epoxy drys. Just my 2 cents.
