Here's one for you, I'm thinking about adding an Expy IRS to my 97 F150. Anyone have any thoughts on this? It's a hot rod shortbox, not a hauling truck. How different are the frames? I picture getting the IRS and cage out of an Expedition and fitting it to my frame. Guessing that it'll be a huge difference and wholely unachievable without a 2nd mortgage and an engineering degree!

 

Its a cool idea, you might take a look at TRUCKIRS.com .
