Apparently the sun roof seal for the TD5 1998 Land Rover Discovery is also used on a Peugeot but I dont know which model, anyone know which model it is please.

 

I have no idea which model Peugeot... I've never heard that. If you keep an eye on eBay you will probably get lucky. I bought a used sunroof that was in excellent condition for $37.50 plus $20.00 shipping. That was for the entire assembly.
