I'm happy to be corrected about the Dana 60, being a jeep axle, but the Dana and Salisbury diffs are the same, just don't know whether its a 60 or not. Opinions seem to vary:

Re the engine conversion, I don't like it, but them I'm happy with 63hp. But the reason I posted it was that as I said in my orginal post; its
interesting. I just wish there was more technical detail as he's solved a few problems - like the discs, aircon and he's somehow got a modern engine in without shifting the grill, it looks like the transfer case has gone back about 8". I know people post on here about auto-boxes in Series, well he's sorted that and used the original offset diffs, something i believe defeats many who try. I would probably have preferred the whole video to be fimed underneath!
