I'm installing the rubber floorin bits in my blue S1 spider and am kind of surprised that there isn't anything to go under the seats. If you pull a seat forward. you can see the floorpan. Unfortunately, mine has sound deadening material on one side and it looks pretty bad. What, if anything, did you do about it? Any recommendations?

There should be a big piece that covers both sides and goes over the tunnel.

As with most cars of this age, you'rs is missing some bits.

In the nineties, I had the chance to examine a fairly well preserved 1600 Spider. The insulation on the firewall and the transmission hump were all covered with vinyl. The insulation on the floor was missing probably due to some water damage. My thought is that the insulation on the floor also has/had vinyl covering it.

So. I made patterns with paper board for the insulation. Then, I glued some vinyl on top of it. Your car should have a rubber mat that covers the area in front of the parcel shelf such that when the seat back or seat is pushed forward, very little of the vinyl is exposed.

The original sound deadening under the seat for 1966-67 was a thin fiber pad that was covered with a rubber/tar substance. The shape is similar to the one shown by Brian, with the exception it was sort of a inverted "T" shape. It did not cover the areas on the outside of the seat rail standards. It was not adhered to the floor, but it escapes me as to if it was screwed down or laying loose. The front sound deadening was a mix of fiber and tar that was spread over the floor likely in a liquid or self adhering form.
Cheers, jon

The template idea is an excellent one. I happen to have a couple of rubber cargo mats that would work perfectly for that. Thanks!

I believe the stuff is called juke. And yes, it had the black tar stuff on the top.

I believe that the stuff is available from auto upholstery suppliers. But, it won't have the tar stuff on it.

The screws, fender washers and snaps for the rubber mats are all that are holding the sound insulation in my car.

I think you may mean Jute. It is essentially the backing on carpet, without the carpet. I posted what came out of my '69 earlier. It was a combination sound deadening and wterproofing material. I think there are better products today, but you can still find the stuff if you want to be completely accurate in a restoration.

For the solution, I just ended up cutting some black vinyl and laying it under the rubber mats, similar to what ossideseppia did. While working on the dash, I already lost some parts under there and having a smooth surface to reach under and feel around on is waaaaay easier than the alternative.

If you left your convertible top down and got caught by a sudden rain shower, the jute material would absorb excess rain water. The black rubber floor mats would trap water in the jute, like a greenhouse, causing corrosion to form on the floor boards. I believe this is one reason why the floors tended to rust out in our cars.

Here's the original piece that covered the transmission tunnel around the shifter.

Not sure what to call the insulating material. Looks kinda like it might be fiberglass. But actually looks like matted golden retriever hair.

I've never found a similar looking replacement.

You might try using dynomat. It has sound deadening characteristics. Not cheap. Just cut it and it sticks to whereever you put it.

That's what I am using in several places on the car. You can see some under th edrivers seat (installed by the PO) in the images a th ebeginning of this thread. I'm also goin got add it in the rear in an effort to close up the gaps that are commonly seen between the rubber mats and vinyl drapes.

OK, I ended up purchasing some sound deadening material and covered that with black vinyl. Looks pretty good and now I'm not worried about not finding anything that might roll under there.
