As I am fine tuning my van I am now trying to get rid of chassies related road noise. One in particular is my from moon roof. The inside plastic slide over rattles when I go over any kind of bump. I have looked into it and it seems that the within the two piece slide the rear one is bumping against the top of the inside of the roof. I can stop it if I shim a rag or card board between the two slides and keep it tight.
Kind of crude doing that and would rather fix the problem maybe with a cushion on the rear slide.

Can't figure out how to get there.

Anyone have any suggestions on how to get there or a easier fix?

Thanks
