Don't know the answer myself but if you've done the "ring around" of all the usual suppliers and you can't find an off the shelf one try sending a U2U to CK & AK who know someone that can make one up for you, or go on to the UKMonster website and seek out JMo, she got a special zorst made up for her 600 Monnie that is a little different
It's a "bit" more expensive that way so lets hope someone else knows one hanging around in their mate's loft!
