Frame question

[07lbz2500]

I have a set of hangers off of an 83 but there is a problem with using them. on those trucks the frame is straight where the front hanger mounts(like the 67-72 4x4's). Since the 2wd leaf trucks have the same frame as the coil trucks I figured they would mount right up to the frame since they bolt on where the frame is starting to bump. Skchevota did you modify the ford front mounts to fit the frame? Would you happen to have any pictures of the front hanger.

thanks
