I also have a '69 with a small back window. I just installed a '67 cab this past weekend. Sideways mounted fuse panel, no switch location for interior light, etc....everything that was mentioned above. Moving the vin plate on the next visit out back.
Oh, and my '69 also came from the factory with the three-hole gauge cluster. Almost a "zero-option" truck back then.
Now it has a crap load of options in place or pending.....
