An update for anybody who finds themselves in the same situation. I was able to get replacement pivot brackets (bolt on tailgate), latches, stiker pins, and bushing from a u-pull-it yard. Got lucky and found a fairly low mileage '97 with a front end hit and tailgate items had minimal wear.

I also found the "pivot pins" on line from various sites like Moparpartsoverstock.com but ultimately bought them through Amazon because of free freight. With other vendors the freight was as much or more than the purchase. Part number is 55275016.

One shown below installed. Second pic is with bushing on it.
