Threadless stem adapter for 21.2mm stem?

Hello, I have an old GT frame that has a theaded 1" fork I am wanting to use with a 1 1/8 stem. I know there are adapters for this, but I have been searching and searching and can only find adapters for 22.2 stems and nothing for a 21.2. Anybody know where I can find something like this?

They've got them on ebay. Type in "21.1 stem" and they'll come up. Good luck.

Ahhh, that was the key. I searched for 21.2 and came up empty - but now why do they call it a 21.1 when the calipers told me 21.2?

It's .833" (21.16mm), but most call it 21.1.
