Agreed...you may find something for a Ranger that may work, but honestly, anything that is pre-made and specifically built for certain vehicles is way over priced, and wouldn't be worth getting to find out later it doesn't work. Companies like n-Fab will take that price and top it...last I checked, their single light mounts for an 08 Sierra were $125!
You're much better off making something yourself...a friend of mine had plates made (so he didn't have to drill into the roof) that attached to the side rails behind the door, and allowed the brackets that came with the LED bar to mount to that...just went to the local welding shop, asked if they could help him out...one trip to their scrap bin, a cut or two and a bend, for $8 he had his 50" mounted on his truck.
