If you're going to try it, I would buy both the spring cam and the drag adjustment screw, as they could have different threads between the knock offs and the pfluegers. Then just pry up the clip that holds in the break adjustment screw with a flat screw driver a little and you'll be able to unscrew the brake adjustment all the way. Once you have the new parts in place just tap it down. Although these reels are cheap enough you might come out ahead just buying a new one. I have three 1495 reels and one knock off and not one part that I've tried is interchangable. (I tried frame screws and spools.)
Here's a good source for the parts, and for $3.27 for both parts it's probably worth it. But I'd certainly price an American made Medalist just for comparison before I spent anyting rehabilitating a clone. Unless it has sentimental value.
