95 is the funny year!! Interior pieces shouldn't really be that hard to come by, the problem is the color, red, blue, grey's are relatively easy to find and in most cases really clean and in decent shape, however if you've got the 64I or 64D RPO code it can be a challenge to find those pieces ( Tan, Med. Beige, Neutral) I've seen them listed under various names! Oak, Peanut butter, Dark Tan etc...
You didn't mention your color of interior, but as stated above, the colors starting in 95 and up are not to hard to come by, by the time I hit the pic-a-part yard the trucks are stripped and what's left has seen way better days!
Most of my internet searches (your best friend) that have good parts have been from your neck of the woods, I have also seen a lot of interior trim pieces in excellent shape from the East coast as the humidity has been more forgiving to the plastic than the dryer climate of the west coast!
Yes, the seat belts would be a one off deal, just have to look at the listings close.
