These covers are done and installed with shiny new twist snaps. To get the dimensions I mounted the bunks and measured. I made the covers rectangular, 14″ wide and just as long as the roof cutout. I wonder if the originals were not rectangular and instead had a flap to cover the rest of the bunks? They stick out in front from under my homemade covers. I won’t be changing mine, soon.
Will add pictures to the website when time permits.
