Ok I found a roll bar for my Stepside Ranger. The dimensions were originally 40 inches wide from the front flanges and about 35 inches wide between each rear kicker, (meant to fit a regular bed). The problem was the bend in the bar going up was hitting the sidewall of the bed. I needed to cut about a 6 inch sector on the top pipe and reattach the two. Ultimately it was a success in mounting and it looks great.
For you guys out there thinking about getting one, you can buy roll bar that fits a regular bed and make your adjustments. Its not hard to cut the bar to make it fit. I reattaches the bar by putting a PVC pipe inside and securing it through bolts. No welding required!
