You mentioned in your post, "it just isn't the same in the set that I've had for years." I support your sentiment 100%. The father of my high school sweetheart, the girl that I have now been married to for more than 57 years, gave me a 3/8 drive socket set of Wright sockets for high school graduation. I have scores of other tools but I don't care even slightly as much for them as I do my Wright sockets. I recently had to overhaul my ratchet and I was able to find a rebuild kit for it on Amazon. They are still perfectly good and the chrome is still shiny.
I would suggest that you look on ebay and Amazon. I think there is a very good chance you'll find an authentic replacement.
