I have the same truck as you, 94 XLT, cept mine's the light grey leather interior. I was going to do something very similar to yours, however i have a few questions....
1) Where's the 4x4 buttons?
2) How'd you cap off the vent that's supposed to be there?
3) WHY DID YOU LOWER A 4x4 VEHICLE? :)
Also, out of curiosity, how much time did it take you to make the custom dash insert? Is that fiberglass, or it almost looks padded and vinyl'd?
