Oh, one other thing I did last week was order a number of samples, both for the paint as well as for the interior carpet.
I found a great website -
StockInteriors.com - that does molded interior carpets in a ton of different styles and colors. I'd already ordered a number of their lighter tan/beige samples trying to match the original, but now that I have the seats and trim color determined, I'm thinking that a darker brown would be both a nice contrast and show less dirt. Fortunately they have a number of medium to dark browns in the 80/20 nylon loop, so I ordered up some more samples. I'm thinking the middle brown will be a nice contrast without being too stark.
For the exterior I've decided to do a DIY bed line paint job. I'd originally thought of doing just the white of the two-tone in bed liner because that's the area that will get most of the trail rash. However, on researching bed liners I found that Monstaliner has a number of yellows available. At least one of them reasonably well matches the original yellow of the truck. Doing both colors in bed liner would keep the texture and finish of the truck uniform and protect the whole thing. And keeping the yellow reasonably the same would mean I could do only the exterior in bed liner instead of worrying about doing the door jams as well since they'll, at first glance, match. I ordered up samples from Monstaliner as well just to verify the colors. The first is the white I expect to use since it is a slight off-white like the original. The next three are the yellows I'm sampling. The first is probably the best match, the second is more of a bright / Corvette yellow, and the third is a school bus yellow.
EDIT: I've also found SEM has a tint-able bed liner which is allegedly available at Finishmaster. However each Finishmaster store apparently has different product. So I'm gonna call around today to find out if A) they have the stuff available and B) they can tint it for me to match the original truck color.
