Ok everyone... I just have to make absolutely sure before I sell someone something that won't work. I know that the A6, Z6 and Y8 cam gears are all the same in terms of actually fitting onto the ends of the cams, but which ones are completely identical? The way I remember it is that the A6 and Z6 are keyed the same, but the Y8 cam is 4.5 degrees different from the A6 and Z6 cams. If there's someone out there who knows for sure, please tell me if I'm right or wrong.
