Possibilities of Firewall Smoothing

Iíve decided to try and get a clean look by smoothing the firewall and I was wondering how much can I do without taking away certain things like windshield wipers? If there was a way to keep this stuff just in a different place then Iíd appreciate any info. This is probably not very clear or informative but I have these pics. In other words I see a lot has been covered up and I was wondering how to replicate that to keep the function of the things that have been covered or if the function of those things is even applicable in these builds.

Re: Possibilities of Firewall Smoothing

I just did this myself came out pretty good. I started with cardboard template then went to a piece of sheet metal. Iím going to use a hidden wiper motor setup so I deleted that hole. Also had to weld studs in place of the gas pedal assembly. Iím installing vintage air so only needed 4 small holes under passenger fender for the lines. Here are a few pics.

Re: Possibilities of Firewall Smoothing

Looks great. How did you attach the panel (spot weld, bond, full perimeter weld, combination)?

Do you by any chance know how or what parts the hidden wiper motor setup uses Iíd like to cover that part as well. Thanks for the pictures

I also noticed that the fender mounting spots look different but Iím not sure if itís already different on a earlier model than a 70 like mine but if you did something could you explain it to me thanks!

Look through my build. I used a worm driven wiper system and mounted the motor in the kick panel vent.

Possibilities of Firewall Smoothing

They spot welded the panel. Used seam sealer on the sides and a very light bondo filler. Several companies make a hidden wiper system I still need to look into which one Iím going to use, they are pricey. The fender mounts in 2 spots, 1 on the firewall which I just cut a hole in my sheet metal slightly larger then the original to allow for proper alignment of the new panel. Hope that helps.

So would the hidden wiper system be concealed under the driver side fender like in the same place where the blower motor was just on the other side

This is what I’ve done. I kept the original wiper location and will be putting and aftermarket motor in place of the original. I left the original firewall and perimeter welded two pieces of steel on the ground the welds. I placed some 3m glue between the panels. Little body filler and some good filling primer and I was in business. Car is being all home built.

Cheers.

Home built here as well and looks nice. The aftermarket motor will be quite a bit smaller correct?

The unit will be a little smaller for sure, and it will bolt up in the factory location. Just didn’t want to have to do more work than needed for a street / strip car. Still looks ok in my opinion. Haha
