I’m going to open a new thread because it moved away from the actual question: I’m considering converting a 78 F250 460cui from 2WD to 4×4. I would only buy the vehicle if the conversion was manageable… Material would have to be at least 1 distribution gearbox with flange part to the transmission, 1 front axle with the same transmission as HA and 2 other cardan shafts What about the entire axle suspension? Steering is certainly different, isn’t it? Some things in question (Dodge, Chrysler, GMC, Jeep) or should it come from an F250? Up to which years of construction you can look there? The net is full of parts, but what fits there and what does not, I have no plan. Just as an example:https://www.ebay-kleinanzeigen.de/…/995516286-223-2866 I want to be able to estimate what comes to me. Not that I open up after a huge construction site, which will never be finished. VG Mattze
