I thought that was what we were trying to establish.  If the steel rims off several different Fords fit they will be cheap to pick up at a salvage yard.  This will be useful info for those of us that are cash strapped or can't justify $1000.00 for a second set of shoes for our Jeeps.  Ebay maybe good for a lot of things but the shipping for rims would be more than a new set.
