I found a few, but either discontinued or out of stock, and I'm guessing they won't restock. I'm so pissed for breaking it. But they have a small gap with most atty's, and I thought I could just tighten it up a bit. I thought wrong.......Looks like it's discontinued at FT. IIRC @JuicyLucy or someone else was looking at changing the 510 setup in a CV.
The actual pin. Right where it screws into the top of the bottle assemblyWhat part of the 510 broke?
