Jerryatric,
First thing to confirm is the size of your truck. Your thread title says it's a 4400, but you are calling it a 1-ton. The 4400 is a 1-1/2 ton, a 3800 is a 1-ton.
If it's a 4400 it will have the "big truck" front fenders and grille. The wheel openings will be about 42" wide at the botton of the fender. The fender will also have a larger flair than the 1-ton and smaller truck fenders.
The only 4400 parts that are common to the 3100 are the Hood, inner fenders and Cab, that's it...the frame and suspension parts are way bigger (3100 vs 4400).
Let us know what series truck you have so we can correctly answer your questions.
