Well the AV stuff will bolt on the same as on the Stihl stuff and if your the only one who knows well how can the value of the saw change ?
The chinese parts dont have made in china writtan on them i can tell you for sure.

The early model AV parts will, the late model I don't think so. As a late model 090AV crankcase is different from the early AV/non AV crankcase. An 090AV is largely a collecter's item today, few Westerners use them on a professional/ everyday basis. Collecters want the real OEM saw not aftermarket. Like with any other collectible.
