As you can see from the pictures my truck is a little bit rough. I have already installed new patch panels on the cab and doors. The fenders and grille will take time to get straight. The plan is to install motor behind the cab for more cab room and make a regular pick up style box. A bit longer than most though. I am going to try and make the box with the same body curves as the cab. I will be looking for some ideas along with some parts soon. I will keep you posted and ad more pictures as soon as I can.
