I'm thinking of making wood side boards that go in the bed pockets,was wondering if anybody has any pictures of some to get ideas from,I'm thinking 2 6'' boards would fit without going up to rear window,blocking view.Thanks

 

You can look at my 48 in my gallery. Think I went with two 4" boards. I can measure if you need specifics.

Not a '51-'52, but this '53 I used to own came with 'boards. Not entirely easy to live with, because I couldn't see between them for side vision, so make sure your boards have a gap or you have good mirrors! Not meant for show, obviously, but these were great for hauling stuff.
