You can get a brand new Febi for about $130. Not cheap. Or, you can try out the "Hans" (aka Prothe) Made in China $hit for $55.
Here's the part number:
028 109 101 F
Or, if you want, I could meet you in the middle. I have one that I ran on my 1.6NA hydro motor for a while (about 25k miles), as I couldn't find the correct hydro camshaft at the time. I bought it brand new. It's Febi and was made in Germany. The only reason I pulled it was to try a correct camshaft and see if my MPGs would improve. They didn't get better, but they didn't get worse. I'd sell it for $75. I just pulled it about 3 weeks ago, so it's fresh with oil.
PM me if you're interested.
