Well, being a nube, I didn't even know what a Level 10 upgrade was. All I knew was that the parts for the regulator and the on/off button fit just fine, but the stuff for the powertube just didn't match. Much research later, I realized that the standard Automag/Minimag oring kit doesn't include the Level 10 parts for the powertube. I guess this is because not all classic valves had been upgraded, and the reverse problem would exist for those folks if the oring kit had the Level 10 parts in it-just a guess. Anyhow, I got online with AGD and ordered the parts to do the "front half" of the valve, Level 10 parts: Powertube Tip orings, shims, carrier orings, powertube orings (goes inside the carrier), back washers. Works like a champ now. Just look under "Level 10 Parts" on AGD's website. There isn't a kit, you have to buy each part separately.
So, the lesson I learned was to know what parts I needed. Check your powertube parts against one the may parts diagrams out there and see if you have an earlier version of the powertube or the Level 10 kit on it. If you Have Level 10, get online and buy the rest of the parts.
Hope this helped. I went through a weeks worth of research to figure it all out.
