Sidestep beds are really hard to come by here and the ones I do find I noticed are rotted in the same spot.
However, in a stroke of brilliance as I was looking at the bed I thought.. I wonder if the right side is just the left side in reverse. Sure enough the back left is exactly the same as the front right.
So since my back driver side part is rusted, if i can find a stepside bed I can cut the front passenger side out, turn it around and weld it into my back driver side.
So the hunt for a stepside bed is back on. lol
