Update directly from Cherry corporation:
The part # for the kit is G99-0745. It will come with the plastic mounting pieces and the metal bar. You can try Arrow, Allied, Newark, Marsh, Online Components.com, or Master Electronics. This is not a very common part # so they may need to special order it from us.
So I will check with the listed distributors to see who has stock and the pricing. Maybe I should personally do a group buy on this....
