need rear window lever for 88 impulse

HI. I have an 88 impulse that my parents purchased new. It has 47,000 mines, is in very good condition. It has sat for the past 10 years, so decided to put it back on the road. I do need a few small things. I would love it if someone could steer me in the right direction. I need the lever for one of the rear windows to start with. Hopefully someone will be able to help me. I have been everywhere, over and over on the net, but have had no luck. Thanks for listening, litl red

Want to share some pictures .. Maybe you want to sell it ..
