I just read the custom classic trucks article, it is a good article with good pictures. the only thing that kept bothering me is they have the years wrong on which ones had vent windows and which didn't. They kept saying 52-55 did and 47-51 did not.
The 51 actually does have the vent windows.
I really like the power windows kit they used becuase it kept the original syle window crank handle to operate the power windows. That is pretty slick.
