I'm Doris from Switzerland. I don't know how you call this part, so I thought to start a new Thread.
I hope you can help me ?
My boyfriend and I have a GMC Vandura, 1989. We are fixing a lot of things.
We are seaching for this plastic thing.
Hope you can help us and say us where we could buy this item ?
Thanks a lot for your help.
