a buddy of mine is takinga 5" off his reg cab with an 8ft bed and i was wondering if that will fit on my quad cab with a 6ft bed. they look to be about the same length/wheelbase. any differences? hangers in the same place and stuff?

 

only 1 way to find out. it will fit, the worst thing you will have (or might have) to do is add a hanger in 1 spot maybe.
