Yep, that's the one. It was my mistake. The angled flange is on the bottom of the stem. And it's already in the low position. It's been a long time since I'd worked with these. Anyway, if you want to lower the stem without cutting the steerer, you need to get a standard 1-1/8" x whatever your handlebar diameter is. Oh, yeah, and the slots inside are supposed to be lined up perfectly longitudinally so the handlebar doesn't tilt to one side and the top cap seats properly.
