HELP!!! I acquired a 02 Regal LS with a sunroof issue.Either someone frankensteined this sunroof or I'm missing something.All the regal sunroof assemblies I have found in the supposed compatible year range do not have a seal on the body/roof.They seal similr to the GP's,Impala's etc with just the seal on the glass closing against the body and the drain system doing the rest.My car has a gap and shows evidence of another seal that was fitted to the body.I have no history on the vehicle.The assembly that is in the car is GM and even has the typical GM candybar relay and wiring.I'm posting pictures so maybe someone may of encountered this before or a sunroof guru can point me to obtaining this seal

Wish I could help, but my knowledge of sunroofs is limited to looking out to the sky.
Other problems, maybe a better chance.
