Thread: Mounting shit under dash

Tweet

As mentioned if your firewall is painted you will need to go another way. But instead of welding a Bolt by the head. A much nicer look can be had by using elevator bolts. These have a nice and very wide head for welding, and can be had in almost every size from 1/4 up to 7/16.

Nice job heatwave, that's the cleanest firewall I've seen in a while. You and Ken do fine work at hiding all the busy stuff!

My Willys is a plastic car and has a smooth firewall. I too did not want any holes in the fire wall. I mounted (glued) a piece of 3/8 Birch ply wood to the inside of the firewall. It has a number of 1/4-20 blind fasteners so I could add a second 3/8 Birch panel. Purpose being that if i really didn't like what the second panel did, I can sort of easily change it. Everything mounts to the plywood.

I even have the ignition box and coil mounted to it. I have an MSD pass thru for the coli wire that you can hardly see under the hood. The only other hole inthe fire wall is for the throttle linkage and it has the Lokar cable running thru it.

It is a lot of extra work to do the clean firewall but I feel it is worth it.

My car is not very big under the dash so there is a huge amount of wiring wrapped up under the dash and in the kick panels.

I must say that a lot of really good suggestions have been put forth. I can't speak to firewall hangings as all stuff was put in the old fashion way..... nuts, bolts, screws and rivets.

Heatwave, thanks for the picture of the underside of your dash. My 'glass '29 looks similar at this point so your picture is encouraging to me.

For ease of access later and to keep things out of site when the wiring is done, sometimes a panel attached under the dash and hinged with a piano hinge makes working on the under dash components easier but keeps them out of site when you're cruizin'....I secure the hinged panel in the concealed position with either dzus fasteners or screws....

very good idea Dave. I hate working upside down under the steering wheel!
