--John Deere became Oshkosh, or the other way around, and now they are Freightliner. Try contacting Freightliner, they usually stock the parts..Your local Freightliner dealer is the best bet, but home office in Gaffney, Sc is 1-800-385-4357. Ford parts probably will not fit.
My 90 Cruisemaster was on a John Deere chassis and I was surprised at the support by Freightliner... Hope this helps.
