50 amp 90 degree connector where to buy

I not looking for an adapter. I am looking for the connector to install on my existing cable replacing the faulty one. I found them years ago but can not remember where. I have a new end for it but would really rather go with the 90 degree version. I know camco makes the adapters in the $50 range and I could just put a standard 50 amp 4 pin receptacle on the end of my cord and use the adapter but it is just not a clean as having the proper connector.

Thanks for the suggestions
