Well after sitting on the F6 for months, I decided to have some work done. I have a local acquaintance/mechanic who is helpful and willing to take on working on the old stuff. The truck is in his shop awaiting a transmission rebuild. I have decided that for my purposes the truck needs to be a flat stake bed. The tank was very far gone inside as far as rust goes. Here are some pics with the tank removed. Thank you again to this community for the invaluable information.
