The Stovebolt Site Forums The Shop Area Paint and Body Shop Doors Strange find inside the doors

We've started overhauling the passenger door window assembly and found some strange stuff at the bottom of both doors. It looks like a strip of websuit material about 18" long, 2" wide, and 1/2" thick. I'm assuming it was some sort of spacer between the door skin and the horizontal support halfway down the door. The passenger door has what looks like a thing paper booklet folded in half and shoved in that space. Is that supposed to deaden the "gong" sound when you close the door?

sounds like something a PO added for something they thought was a problem [irritating] - the only factory material I've seen in a lot of different doors is a heavy tar paper like material, mostly stuck in spots on the back of the removable panel, never anything thicker .... the best way to lessen the door closing noise is to coat as much as reachable of the inside surface of the skin with an undercoating material

FWIW, there was a similar black foam type of material in my doors at that location as well. It ran the distance of the support bar but was only about 1" wide (the width of the bar). I just figured it was there to help reduce some outer skin vibrations.
The doors also had the tar paper vapor barrier Bill mentioned.

Hmmm. Well I think I'll pull out the paper catalog in the door and just let it be. There is no way to put anything back unless I pull the latch mechanism and that isn't going to happen.

The Master Parts Catalog has a good illustration of the door on page 585 called "Conventional Cab - Exploded View". It shows the "insulation" material sandwiched between the door skin and the braces. A 16.xxxx section number part number is not offered. Mine were rock hard When I knocked them out. The indention shows that the material was soft when it was pushed in there at the factory.

So I have the same question. What is a suitable alternative material?
