Oldsragger

Hello, its hard to get parts here in my country for my 1979 Oldsmobile delta 88 royale..

So i Wonder if any know what other cars the parts can fits over, like Frontwindow, and sidedoors,,rubberseals With the Windows...etc.. and this body rubbers between tha chassie and frame.

i have hear that window from Chevrolet caprice can fit, but im not sure what year... same like doors maybe...

have any some ideas? thanks
