I bought a 7.3idi core engine from a guy near me earlier this week for 200.00 and was talking with him and he told me he had some extra parts laying around, so I said sure ill take them off your hands for you so he gave me another ZF5 syncros are bad in it and he went on to say he had another clutch kit for it. I thought to myself I could use another DMF just in case, lo and behold it was a very lightly used LUK SMF and clutch with the pressure plate. I about fell over and smiled and put it in my truck. Question is I know the flywheel bolts are different, are they longer or are they shorter, does anyone know an exact length on them or where I can get replacement ones.
