I know this is a longshot, but I figure I might as well ask. Anyone have a Star 1" threadless headset they'd be willing to part with? These were sold on Euro-Asia Imports and have a super-low stack height (claimed under 20mm). The product page is still up on Euro-Asia, not sure when they stopped selling them.

I'm working on a vintage build and am trying to deal with a steerer that's just a tad too short (and a Kooka stem that's inconveniently tall), so the low stack height would really help.
