HH,
From the factory A/C units I have seen, yes the thin rubber is used. It has been suggested to me to buy an inner tube and cut to fit.

Thanks for info. I have only seen it on a well used car and that was torn & looked like sheet rubber or maybe the inner tube. Split or torn and was held on by baling wire. Used the sheet rubber again when I worked on the car many years ago but just didn't look right with the slightly different size and angles between blower and dash openings. Recently cast one out of urethane foam when I did the inside ducts but made it thick. If it's supposed to be thin, will probably make another about half as thick.

Here is the reply I received from friend Chris.
"Randy,The blower housing is a preformed molded rubber with no seam.I would have to look at to get diamentions but it is the same thickness as an automobile inner tube.Thats what I used.The duct work is like a thick molded rubber but heaver than foam and that is why Packard had the 6 inch wire extention for the rear speaker.Chris" I hope this helps a little Howard. I attached pics of Chris Caribbean with A/C.

Thanks Randy. I made the first one 3/8 thick like the ducts but will redo to 3/16 or so. The urethane I used on the ducts is flexible foam but may be somewhat more dense. It skins over to make a smooth surface. I think it looks and feels virtually identical to the originals so all in all, I was very pleased with those. Now if I can just get the dash top ducts and glovebox to come out as well.

Would you please post information on the foam -- brand and source? It sounds like an excellent material to work with.
Thanks, Bernardi

Here it is..http://www.reynoldsam.com/Rigid-and-Flexible/c10_1121/index.html
The one I used for the ducts was the Flexfoam-iT 17. Also used their black pigment. One word of caution when using this stuff. When they say it sticks to almost anything, take heed. I used fiber board for the molds and thank goodness I experimented a bit first with some scraps. Wound up covering the forms with aluminum tape & then followed their instructions and used both the Sonite wax and the Ease Release 2831. Because of the turns and angles in the form, it would have been a lost cause without all 3. For the 3 duct pieces I did, one trial size was enough. EDIT: I think Reynolds is a dealer out here. The Smooth-On main office is closer to you.http://www.smooth-on.com/Rigid-and-Flexible/c10/index.html
