1987 Buick Lesabre Wagon parts
 

Hello!
We are a workshop based in Italy and we work mostly with American cars.
Right now we are working on a 1987 Buick Lesabre Estate Wagon for one of our clients and we are looking for some parts for it...
The rarest parts we are struggling most to find are the impact rubber strips for both bumpers, the outer window sweeps and the trunk door seal.
Also we are looking for the headliner molding clips, the ones in the pics below.
Can anyone help us out to find the parts we are looking for? :)
Thank you!
