Clay Smith Engineering was right by my house growing up - just off the Fullerton airport
Grave Digger also was right there (or maybe - one of the Grave Diggers? Seems like they ran/run multiple trucks under the name).
Fender was in the area, too (Fender guitars)
Sun tach, Mr. Horsepower sticker, and you have find some Gabriel HiJackers and jack the rear end up a bunch so you can fit big wheels/tires in the back without mini tubbing...
