Well I thought I had a plan until I followed your link Stuart. The description of the cable says it will not work with gear reduction starters. I assume that it has to do with the gauge of the wire. I replaced my alternator wiring with a kit from one of the usual suspects a while back and I'm wondering if my kit had or should have had the same foot note.
