My 95 f250 has a homemade flatbed on it that came with the truck. I like the bed but the mounting brackets on it literally make it set 6inches above the frame and it looks well crappy. I would like to lower it down closer to the frame but not sure how to attach it to the frame. Can I make mounting tabs on the bed and use the original factory bed mounting holes on theframe and bolt it directly to the truck? There is no 5th wheel or anything on the bed but I worry about making the frame to rigid with the bed bolted to the frame.
