Please let me know if you find a source. I only need the driver's pad, the other three can be dyed. Odd that no company reproduces these, as I believe they were the same on '64-'65 B bodies.
There is a company that reproduces these. Layson's sells them but you can get them direct.
The company is Auto Medic Supply 866-441-7039. They
are $50.00 a pair, come in black or white. The white are intended to be the
ones you would purchase to spray dye if you have an interior other than
black or white.
Here is the website, http://www.oxygensensors.com/ but you will find nothing
there about the armrests. This is a new market the owner is getting into,
and he is also doing the front and rear bumpers. I'd suggest phoning them.
