Can anybody tell me what the difference is between the 90mod F150 and the 97-00 F150 as I'm looking at some air helpers from a 97-00 that bolt to the out side of the chassis & sit on the top of the spring

I can't say for sure but generally the difference is either height between the spring and frame, or OEM holes drilled into the frame making it easier to install. Best to contact the manufacturer in this regard as to get an older unit to work in terms of installation would just mean you would have to drill a couple holes into the frame rail to install the air helpers.
