The plasctic part according to newmar is not their part. They buy it from a person who has patent on it, and he sets price. That is why it is so expensive. We could band together and reverse engineer it, and then have it made out of glass filled nylon, which would strengthen it considerable, that would or might make it stronger, but it might be more brittle. It's been redesigned a bit according to the parts person I talked to, I don't see any difference. I was not aware of the latches being from another place. If I have another issue, I will order some extras. If I had band saw, could make template out of wood or something and then cut them out of pieces of plastic of some type. Lot of work for small part which might or might fail again. I guess a survey of "latch failures" might be in order to see what numbers we are talking about here. The plastic thing looks to have some machining on it, I am not sure if it's injected molded or not, I will inspect for parting line and other signs it was. They might be machined in jig by the hundreds or so.
