Thank's, that's good to know. I read all about when the pin is not seated the unit won't fit right and how some people think it's in and it isn't and then they crank the screws down tight with a wrench, forcing it on. That puts lateral pressure on the bearing and it fails quickly. In this case the pin was definitly in the right slot as I measured the housing both seated and not seated and used grease to see where the pin touched. I was able to tighten the housing down with just my fingers turning an allen socket, it took very little pressure to seat the unit. All I could see potentially wrong was that maybe the "cloverleaf" indents for the cam bolts were not as deep as on the MSD unit. I am just nervous as these things are so failure prone.
