Buck,
Yes, my bed was off at the time, but I was surprised at how little force was needed. I was not swinging for the fences at all. Remove the tapered lock pin, set your drift on the inside of the frame, and once it starts, it should come fairy easily. If not, Pb blaster it. Soak, use the heat carefully. Try again. Good luck.
Edit: I just watched that video shared above and my spring mount on the frame is different. I have a Canadian GMC one ton (Chevrolet frame). The perch on mine has a hole drilled so you can access the backside of the spring busing pins. If yours doesn’t have this, my help has gone out the window. I’ll try to get a photo of that hole for you tomorrow.
