Mikuni VM29 29 smoothbore problems, need parts

Hello All,

I'm working on my '78 1000A and recently bought a set of "restored" 29mm smoothbores. I installed them and checked the synch and they were out of spec. I began to synchronize them and while I was working on carb #4, I heard a snap from carb #1. The link lever assembly is broken (#80 on the diagram below). I can't find that part anywhere. Does anybody know where I can get that part? It's Mikuni Part number Vm29/17, link lever assembly.

Thanks
Mike
