Yet another GMC build

[OKGMC4]

Old frame out. New one shoved in. Everything I could find said that a 58-59 frame is the same but front frame rails need to be shortened and bumper bracket holes redrilled. I found my core support holes don’t line up by 3/4 to 1 inch. Since they are riveted, removing the frame brackets and relocating them will be super fun. That was sarcasm. I was hoping to have that booger bolted tight today. On a side note, I think you can actually see how warped my front frame rails were in the photo.
