I am having issues with the DS door on my 56 3100. It literally jumps up and down as i pick up speed and am on uneven highway. My door does not have weather strip in it as of now, is that likely the main issue causing this? Or could it be an alignment issue? The door closes and opens good, looks aligned from the outside. I have the weather-strip, but am holding off putting it in until i paint the inside of the cab. I am basically doing a build, area by area, so i can drive and enjoy it during the process. Hope that makes sense. Appreciate any tips or info around this.
