Bilstein 5100 problem

So have an issue. I have eibach 2.5 coils and bilstein 5100 and love them but having an issue, I used the factory top plate and the hardware that came with the shocks but now their loose and has play in them, I've tried tightening it but the center doesn't have any thread left and I can't tighten them any one. Anyone ever have this issue or know what to do? They squeak a lot and you can move my shock and it looks like it's actually hit my sway bar before

I can't tell because the video is playing in ultra-wide screen mode on my computer, but it doesn't look like there's anything in between the coil and the upper bracket/brace/tower. seems like there should be more length in the whole strut for some reason.
