G'day everybody. I have found out how to add a pic to my post and think this will make it much easier to get the help from you all that I am looking for. The truck in the pic has 20 inch wheels and the rear are duals. I'm wanting to turn this into a pickup with a tub on the back and am really wondering about the front fenders. Are they different between the various sizes of these trucks, ie is the shape of the wheel opening larger and smaller? Are there many differences underneath suspension and steering wise etc. Thanks. Ron.
