Hi looking for some pic of the origanl 67 converable all the floor underlayments
-
Interested in the shape of each piece or a cross section to get an idea of how its made?
-
Regarding Jeffs response I'd like to see both. Shapes and make-up.

The make up would be the same or similar to what was reproduced in this article posted on this site
http://www.concoursmustang.com/filevault/Articles/Article_Trunk_Underlayment.pdf (http://www.concoursmustang.com/filevault/Articles/Article_Trunk_Underlayment.pdf)
Same stuff was used over your gas tank
Checked and I don't have any pictures of the floor underlayment on a carpet - its either covered with carpet or nothing

Jeff very nice article. Wish there was a way to enlarge the pics so as to see it better. By the way the few converts I took apart in the 80's did have this type of material on the floor pans and transmission tunnel, floor pans rear and I believe under the rear seat as well. Wish I had documented it back then and not just thrown it out. Here is a piece of the material I've been saving for my car. Can't figure out if its from a 68 or a 70 Boss 302 or possibly out of a mid eighties Dodge XXXLong passenger van (made a great cheap tow vehicle when i raced so no jokes).

Looks like from the van

Ok i'm going to try making the composite. i have a set of the snake oyl jute and asphalt type covering. I also have an old set of thick rubber sheets I purchased from snake oyl back in the eighties. I will glue these together and forgoe having to tear some of the jute off a second set. The question I have for you Jeff is are you heating the stckey black side of the jute composite is so that you use it as the glue to attach the kraft paper? I believe you trim the craft paper once it is adheared onto the pad?

We used spray adhesive to attach the jute to the second rubber layer (after we removed that jute layer) Then we heated the tar layer on the outer surface and applied the craft paper (one side at a time
I believe you trim the craft paper once it is adhered onto the pad?
We trimmed the composit (tar/jute/tar layers) sections then trimmed again after adding the craft but I think a better, sharper edge would be produced if we had left the cutting of the shape until the whole thing was assemble. We used some extra craft paper to make the cut pattern.

Will give it a try weds. I may be back with more ?'s

Jeff I had to put the engine work aside as have a small issue with pulleys. Wrong one got installed during engine build. So that left me with a choice on how to spend this holiday and I decided to try the underlayment project. Not as bad as I would have expected and managed to get some help from my older son (he's ussually too busy with friends). I was fortunate that i didnt have to get two sets and strip the jute as I had a very old set of heVY snake oyl asphaltic/rubber ccompound underlayment along with a new set. It made for a very nice composite. The old mats were time consuming to heat up but heavier weight like the originals. Will post some pics later. Only need to add the oil but will hold off until a couple of days before install.

Here are some pics of the composite underlayment done on Monday. Oil is the last step. Thanks Jeff for the tutorial on DIY. The 5 main pieces are done but I have one more left which snake oil referes to as "Transitional Piece" Supposedly it goes behind the rear seat. The old heavy weight set from the 80's didn't come with this piece and I dont remember a composite kraft paper type pad on the rear bulkhead. Floor yes but dont remember on the bulkhead. Maybe just jute? So Im wondering if I need to construct a composite or just use what was supplied by snake oyl with no paper covering?

On 67's I've only seen them all the same - as cut from the same bulk sheets and by the same supplier. Saw an original one (over the top of the rear end area on a fastback) and it was the same multiple layer with the dark paper finish

Well my project is a 68 and a convertible. Just can't remember that far back. What have you seen regarding that model and year.

No real room to put one on a convertible (transistor over the rear end area) I believe

Here are some coupe examples - no real good picture of the shape - just that it was commonly there

Well lets see how the WIFI works up here in the wilds of northern wisconsin. The first pic you show jeff is exactly the area in question and you show a convert. Doesnt seem too be any evidence of a pad on this bulkhead area (the verticle metal with the pocket for the power top pump and seat back. Looked at the assembly manual for interior and on page 49 the pad is shown below the rear package tray but it is on a coupe and even refered to as part C8ZB-65. So at this point I believe thios piece does not apply to a convertible.

Thought I'd resurrect this topic with a few recent photos that I took of my original 1967 Convertible underlayment, and the Ssnake-Oyl replacements...
I'm not sure if I've got all of the little broken pieces exactly in the right spots, but the first image is the original asphalt underlayment and the padding that went between the underlayment and the carpet - or perhaps this padding was originally attached to the carpet (more about this below). Unfortunately, the original black carpet was very moldy and I had to throw it out many years ago, so I can't check it...
The second image is the Ssnake-Oyl replacement underlayment pieces next to the original padding. I do like the Ssnake-Oyl pieces, but for some reason, they put the fabric backing material on the wrong side...
The third and fourth images show the original backing material on the underlayment - sort of a jute fabric under all of the pieces except for the transmission tunnel piece, which is more of a plastic wrap material...
The fifth image is the backing on the Ssnake-Oyl pieces - a plastic similar to the backing on the original transmission tunnel underlayment...
The sixth and final image is a label I found on the underside of the rear floor padding. It looks like it says "RUG" on the top line, then "C6ZB-76 I ..." on the next line, and then "V BLACK" on the final line. It's because of the word "BLACK" that I'm wondering if this padding was originally glued to the underside of the black carpet, as there would be no reason to label just the padding itself as being BLACK...

Yes the jute backing (as it is on reproductions) was originally attached to the carpet back - unlike the underlayment. Sometimes you'll find a stenciled (sprayed) part number and identification rather than the paper label
-
Jeff is correct the jute was attached to the back of the carpet. Here is a tag from our 67 GTA convertible and a original carpet sample. I wish we could get carpet like that today.
