Wish this were good news
Ken,
I am looking for the same thing for the right side of mine. Occasionally they pop up on EBAY, but not nearly often enough. I am told that the brackets aren't even available anymore, and the gates cost over $300.00. So far I have just decided to deal with no reverse on one side. I am looking into boat junk yards at this point. Will let you know if I get any hits.
