Rear window. ( not Alfred Hicthcock)

Me again, sorted, the door seal around the roof where the window resess into is knackered, the aluminium has rusted and powered swelling the seal so the window hits that and retracts down as if something is in the way. Cleaned the seal out and managed to push the window in as is went up. Any idea where I can get a new door seal?

New one about £300.


Can be taken off a scrap car with heat gun and care to melt the glue.
