Interior--46 Hudson Commodore 8 Coupe

Well Jim, I think the original front part of the carpet was not carpet at all but rather a rubber mat with a Hudson enblem in the middle over the transmission hump and it had a a sort of jute backing glued on for sunsulation. However the pack passengers did have a carpet. I'm putting in insulation on my front floor and a carpet and probably two floormats for a more finished look. Dynamat is generally used in door panels and on verticle surfaces and trunk lids but there's no reason why you couldn't use it as a sound deadener if you chose. My interior is almost done and it's quiet and tight on the inside just like a new car. Smells like it too with the contact cement (which is what new car smell is.) Commodore 8's had partial cloth partial leather/letherette available with Hudson emblems stamped into the leather on the door panels. But witth the exception of the convertibles I'm pretty sure they were not 100% leather trimmed. Commodore 8's were top of the line so there wouldn't really be a problem trimming it nicer than original.

In the trunk again the used a rubber mat with a glued on jute backing for insulation and the sides had this sort of upholstery cardboard with a vynil-like surface in the shape of angel wings that were held together with brads and covered the springs of the back seat and the sides of the wheel wells for a slightly more finished look and then the vynil board had a sort of back in the middle of it that took up the movement or air displacement of the center armrest on the back seat (assuming your backseat has a center armrest.)

The trunk lid had a sort of insulation that looks like tar roofing paper. modern replacements might be desireable especially if yours is water damaged.

Here too I used basically the same method as the factory upholstery only I made it much nicer with carpets and insulation and speakerbox carpeting over the side upholstery boards (angel wings). I also made a spare tire cover for a more finished look. I got all my materials from Dubois Fabircs in Oak Lawn IL. at cost but not all are strictly original. The insulation I used in the car came on a roll and was a flame retardant type.

NOW having said all that bear this in mind. In 1946-47 The factory expereinced shortages of stuff and work stoppages. Sometimes on those cars that are totally original you'll even find different fasterners and screws holding things on. Why? Because I read there was a point at which the assembly line would run out of a certain type of fastener and sent guys out to canvas hardware stores for screws and such to keep the assembly lines moving. Also some cars were shipped without bumpers or windows and the dealers shipped then to the customers when they became available. So what I'm saying is you can get away with a little creativity on '46-'47s because although they're advertised as being a certain way, the reality is not all of them left the factory totally identical.

and yes being a Hudnut is disease for which no cure exists.
