I just talked to Ford - they looked up the parts and ordered 3 sets of leaf springs so we can make an F550 out of my old truck. They said its a Ford, so everything else is identical. I'm going to haul 25,000 lbs of mellons between borders.
Naw really - you guys do what you think best. I surrender - I'll mind what I keep in the garage and keep one eye out for parts on the highway in front of me. Have fun -
