Can anyone tell me what cars have a window channel thats interchangable with 85 delta 88 royale brougham sedan or were I can buy a new one I can't seem to find any salvaged ones that are any good and the part was discontinued for this model any input is welcome

 

Any 1981-85 GM B body sedan uses this. Caprice, LeSabre, Delta, Bonneville/Parisienne. The Electra and Ninety Eight may use it but I think their roofline is a little higher.

Possibly 78-80 may also use it.

 

Ight man thanx for the info
