I just got my Cheyene Pickup Parts order, new vent seals are here. And I tore the old ones out, they were a 2 piece design. The new ones are a one piece design. They seem to be a updated unit that dosen't require the sealing caulk. The big question is the vertical piece, the old one had hooks to secure itself to the bar(between the windows). The new one piece dosen't, do I glue it? Cut it? Or what? Thanks guys, oh by the way I need to leave in the morning for a week in the Blazer. Help! Displacement, cubes, and did you say you drive a riceburner???
