Good luck. Never heard of any. The cost per model to develop an OSHA approved ROPS exceeds 10K WITH a guarantee to purchase so many units. No one is going to spend the development money for models, or brands, that are here in insufficient quantity to make that profitable. There are probably 100-200 grey market Yanmars in the US for every 1 Shibaura. Same issue exists with parts.
I wish you well...if you find one somewhere definitely post the source, as it would be new information for most.
