The 22nd Series Custom 8's used Mosstred carpet which is a Wilton wool carpet bonded to heavy foam rubber. There is no binding on the original as the carpet material wraps around the edge of the rubber backing. I duplicated this on my car by purchasing the Wilton carpet material from Bill Hirsch and attaching it to 3/8" thick closed cell neoprene with spray on 3M adhesive 90. In hindsight I should perhaps have used open cell neoprene for a closer match to the original but thought that the closed cell would be less likely to hold water in the event that it became wet. I was very careful about fitting up the carpet and backing material before using the spray adhesive which is like contact cement, so once pressed together it is there to stay. The rear carpet is quite easy but the front takes a bit more care as it has a cutout where it goes over the transmission hump that is not sewn but simply butts together.
I have no experience with 23rd Series cars but the parts book shows different numbers for the Custom 8's so it looks like different material was used.
