Airtex has the pattern for carpeat and headliner, so that's the easiest there.
You can just buy them and they will ship to you,

Everything else, go to a nearby high end auto interior shop.
There are usually really good ones most places, restoring cars.

Specify /supply the materials.
I think Douglas interior has everything, FAA approved (wont burn).
It will be fun for them, and they will do fine work.

This way, instead of the hassle flying somewhere,
or the hassle of shipping things somewhere,
you pop them out of your plane, into back of car/truck,
pop over to the shop and drop them off.
They should be able to do a fantastic job, quickly and reasonably.

Then you just pop the stuff back into the airplane.
So its convenient too.
