My dad picked up a mid 70's FG15-10 for cheap and the only problem we are having with it, is that what ever is supposed to rout the side shift hoses is missing. The previous owner made a makeshift pulley on top of the mast, but it does not keep tension on the hoses. I have been having a hard time finding any info on how it is supposed to work on this model. Any help on this would be much appreciated. I have pics of how it is set up now, but not sure how to post on this board yet.
