Most any paint seller in your area that sells PPG products should be able to fix you up. I only had a two ounce bottle mixed up and it was enough to do at least two sets of door inserts.
Just make sure you ask for the hardner too and also thinner for cleanup.
Specifics on the paint: PPG #902178 - 2003 Ford Car & Truck Interior " Medium Gray Metallic". It's Deltron DIU Interior Basecoat Color that does not require clearcoating. With the hardner it seems to be very durable. I don't have even a mark on ours so far.
I probably mentioned this before but I'd suggest you get a set of door inserts from a local wrecking yard (about $10 each). That way you'll always have the originals. Altohough I have no desire to change them back, it just might be nice in fifteen years to have saved them.
Take care and have some fun.
