Well the doors on my 75 are shot. I have the option of using patch panels to fix them up, but that would require the outer skin and the inner piece, plus lots of body work. I was wondering if anyone has replaced 73-75 K5 doors with either 76-91 K5 doors or 73-88 truck doors. I imagine you can just hack off the frames, but is there anything else that needs to get done? Thanks! It's not what you buy, it's what you build!
