You'd have to look up the cables by year & model you want to use,and then do the same for the 14 bolt using the year & model it came from--offhand I think that "some" might be the same,depending on how they anchor to the backing plate (I know my 14 bolt has a 2 bolt arrangement to bolt the cables to the backing plates)--1/2 tons usually have the type that just poke thru the backing plate and use a horse shoe clip or an expanding sleeve thing to hold them in the backing plate..
Also 1/2 ton ones might be too short ,the drums are 11" on them,14 bolts are usually 13",but they did come with some 11" drums on certain low GVW models..(never seen any myself!)..
