early 110 90 parts

I know it sounds a bit like a stupid question but anyway.
Anyone know of a supplier out the that sells parts for the front doors on early 90 110 doors. The type with the sliding windows. S111 are different so the parts i am after are not going to work. Trying to track down window lock and even someone that may sell the original door trims for them.
Any help much welcome

Maybe try an mod place? Do they have the windows you are meaning?

just a picture to show what type of door i am talking about and the parts that missing.

I'm guessing that you either need mod stuff or later s3. Have you checked the parts manual?
