Hi all- I have a 1997 Ford Econoline. It is listed as an E450 on my paperwork, but you won't find E450 anywhere for that year. It is a cutout that is an ambulance. I have converted it to an RV. It has the 7.3 Powerstroke. I would like to update it to the newer front end to gain extra room for an intercooler in the future. Plus, I think that front end looks more awesome. What years can be swapped to a 97? Thanks!
