Interior: Replacement options for paper firewall liner

[Jeff T.]

I replaced my firewall liner years ago but since my eternal project Lark sits outside year round, leaks and sun exposure has done a number on the liner, it has has curled and faded over time. Also when I pulled the liner out last month, I found where an enterprising mouse had set up shop near the blower motor.

Any suggestions on a better firewall liner than paper and fiberglass bat?

Thanks,

Jeff

I have become a huge fan of corrugated plastic signboard for all sorts of interior jobs. I made the firewall liner for a 63 out of it and have also used it for all the door panels on my 53. It is easy to cut, hard to tear, and waterproof. And cheap.

Oh yeah, and the headliner for the Wagonaire too.

I just replaced my firewall pad with dynamat type stuff from Eastwood. It's peal and stick, (and sticks REAL good) but is a bit messy, actual Dynamat brand, though much more expensive, I hope would probably be easier to use. I then glued carpet to it with contact cement.

I first made this pattern from 30 pack Miller cartons. Thanks to Roland / Topper for a paper pattern I got from him after he did his firewall. I modified the drivers side a lot since the drivers side of my cars firewall interior is very modified. I used the pattern to mark and cut both the Dynamat and the carpet.

The Pontiac Brake Pedal does not look all that different than a '61 to '66 Lark or Lark Type.
What Year Stude. is it in?

Actually the pedal and pad itself is from a mid 70's Cadillac Rich, but the arm and pivot is from a Lark; the pedal was missing when I got it. The throttle pedal is stock but the lever it pushes is a lever and fulcrum that pulls a cable. I made it from bar stock. It's all in my '62 GT. I'm sure you've seen pics of my master cylinder and dual vacuum booster mounted to the firewall.

I have used 1/8" tempered Masonite. But the plastic signboard sounds like a great idea.

Some people have used a product called lizardskin. I haven't tried it, so can't give any input. lizardskin.com
