Unfortunately, these belts are now very difficult to obtain with minimum orders and expensive with post from the EU.  As an alternative, I suggest using a 1.1 metre length of 7 mm Polycord round belting. It's a special Swiss-made machine-tool drive type and very effective and can be joined into the lengths needed for a Toyo ML360. It can be ordered here with full joining instructions provided..
