I have never done a no-vent, but I have just redone the vents on my 57 GMC. I bought all the rubber, new vent glass, and weather stripping at carandtruckshop.com I did not have any problems and they look and work like new. I did buy the rivets and the little setting tool from them also.
The window wipes will have to have the clips trimmed off a little, to fit the holes in the door.
The tension adjusting bolts on the vent frame were almost rusted into. I just brazed them back good, installed the washers and spring and they work perfect.
