I need to replace a broken one, and the auto parts store's O-rings are too thick. Also, does anyone sell replacement holders that have the spring button and two adjustment screws at 90 degrees apart? Th current holder I have is the old style with three screws placed every 120 degrees. Thanks!

I'm going to try Ace, Lowe's, and a local plumbing store. If I come up empty, I'll try Agena Astro. I've used them before and have been well satisfied.

At Ace, in the metric O-ring drawers, I found the part # ORM-204-026 at a cost of $1.39. It's a 26mm inside diameter O-ring, 2mm thick. I tried it there in the store on my 6x30 finder and it works perfectly, including fitting into the finder bracket. I tried a slightly larger inside diameter O-ring, but there wasn't enough tension to keep the O-ring in place when I tried to slip the finder bracket over the O-ring. If you have a broken or missing O-ring on your 6x30 Synta finder, this works great!

I grabbed the SAE version at ACE Hardware for $0.57. It is -026 size, 1/16" width, ID=1.25", OD=1.375". ScopeStuff and Agena Astro have o-rings for 50mm finders only.
