Seems like many people are searching for replacement parts... I myself have, due to not being able to find NOS. I have started reproducing the following tensioner. Made out of polished stainless steel. Wing is slightly smaller, but works perfectly for that “hard to find part”!
$5 each plus a couple bucks to ship. Let me know if interested.
