Ford outers are different than Chevy and Dodge. Chevy and Dodge use basically the same everything with the exception of the inner shafts. Chevy uses 1 u-bolt on the passenger side and 2 bolts, sometimes studs. Dodge uses 1 u-bolt and 2 studs but the studs are spaced closer together than on the Chevy. The Chevy spring mounting surface is 32" on center and Dodge is 32.5. Chevy is 69" WMS and Dodge is 67" IIRC. If you can get your hands on either, do it. I've mounted Chevy and Dodge 60s on trucks that they didn't come from and as long as you are willing to make it work, you can. On my old F-Toy (Toy frame) I had a full width Dodge 60 mounted up and had no problems once I had a plan.
