Yeah this doesn't have me shut down. But makes me worry about "back ordered" parts that might.I don't, but I haven't been too impressed with WW's ability to solve their supply chain issues, been waiting around for a few things since the middle of July.
I would reach out to these guys, as I believe they are the ones supplying the belts to WW.it's great that Eric was able to help out with this part. But I can't help but think that this is not a Proprietary part.
