I would not attempt to drill, and never remove the hinge from the cab. (Only if you absolutely need to) I have removed many doors/pins with success as follows: On the upper hinge, it can be done by yourself if you use a one handed sledge hammer with a long punch, undersized, and then graduating to a punch that is just undersized to the pin. I always soak the hinges for about a week prior to even attempting to remove. Unfortunately, and since the heads of the pins are on the upper end of the hinge, it is difficult and compromising to use a hand sledge and punch upside-down. If really stubborn, I then use my small air cut off tool with a 3" wheel and cut the head of the pin flush with the top of the hinge causing little damage if any to the hinge. By removing the head I can then use gravity to my advantage by driving the pin from the top of the hinge toward the bottom. As for the lower hinge pin, I have removed some with luck, with the hand sledge and punch swinging upside-down, but you are limited on your swing with the running board. If you are removing the running boards anyway, remove them first prior to the removal of the door pins. You can then swing your sledge with the strength of Thor.
It is always advisable to have a helper hold the long drift punch with a pair of Vise-Grips so you can use two hands if needed. Again, if not removing the running boards, or if stubborn, cut the head and drive if down and out. Hope this helps. P.S. Use safety goggles, I was wearing safety glasses, not goggles, and had a chip of US Made steel imbedded into my right eye. I thought it was dirt, but the next day after I awoke, it was still there and boy did it hurt! When I went to the doctor, they had to remove the chip with a large syringe. Also note that good o’l USA made Steel will rust in your eyes, just as on your truck. Be careful and good luck.
