the sideshifter is listed as an 'optional' option. it will not be listed in the mast section of the parts book. and according to the mast number range your showing i'm not sure about that, what hyster shows is not that '215480' range. this mast may be off another truck that was fitted on this truck. that was done alot back in the day. 'mast swapping'.
i think your going to have to get hyster dealer or factory to help get the correct hose group and sideshifter for this.
