extend the sides like in the picture, i talked to my fabricaor friend and he said its best to just do the sides. because if i conect the bed to the cab i want to ake the bed shorter about a foot but that wil be in a couple of years. im going to be learning how to fabricate this week and im only 16:D ive been doing all the body work my self and it looks pretty good, i just need to find out how to give my hood a shape again.
