nah, gas filler neck wasn't bad... just hose clamps and the extension tube. took about 5 mins total.
body bolts aren't too bad. just gotta strip some of your interior out. then you just pry up the rubber plugs with a screwdriver and there they are to greet you.
the radiator isn't really that bad either. it was hard for me, cause my dumb butt took it completely out and it was a pain to get back in.
something else, the isnstructions say to go ahead and put in the steering extension BEFORE you lift the cab... i found this relatively impossible. so i just locked the wheel, unhooked it, lifted the cab, and THEN put in the extension..
the directions do mis print some stuff... but any amount of common sense will account for it...
it's easy.... if i can do it, anyone can!
