If it's like doing 49-54 spindles, the kit comes with bushings, kingpins, thrust washers,shims, and kingpin retainers. Some other misc parts like Jesus clips and dust covers come in the kit too. The Ford ones come with pretty much the same parts, but the difference I have seen is that the bushings need honed after installing them, the Chevys slide in and don't need honed after that.
Never done exactly the ones you are describing but I bet they are very similar.
