I'm selling (6) NOS Door window rear guides.GM part # 20151689. This is the rear window guide and fits all G-body models. These are almost always broken and are the cause of most glass to weatherstrip sealing problems on the doors and side windows. I have (6) of them still in the boxes.$80 shipped for all 6 to the lower 48.I can throw in a nice GN emblem for $20 extra if you want it too. Paypal $2 extra.Please call my cell if you want them 1st. Thanks. Paul 480-221-9572
