My snooping around the net yesterday would seem to indicate that belts down to around 190mm can be had, so I don't think I'll have to resort to that sort of tom-foolery. But first I need to find why that box is crashing. There's a couple questions in the previous post that I am hoping someone can answer. Thanks Erik.
