I just recently had the same problem. I solved it by ordering from Stock Drive Products P/N A 6R51M830060 which is a 1660mm GT2 6mm wide with 2mm pitch single sided belt. For the pulleys, I ordered from Ebay, 4 Aluminum GT2 7mm wide pulleys. I did have to modify them a bit by turning them down slightly in the area of the screws to fit within the bore of the bracket. The fit could also be accomplished by putting a plastic or metal spacer between the pulley and the bearings so they don't rub. Since all 4 pulleys are the same, the system works the same as the MXL inch belt as called for in the plan.
