finally got my new window but it dosent have the weatherstripping, do any of you know where i can find it?
or if/how i could re-use the old one? (doubtful)

 

Dakotas rear windows are encapsulated which means they are GLUED IN with a special urethane. You'll need to take the plastic out from around teh inside of teh window and look to see if theres any hold in plates. Clean all teh old urethane off the pinch weld in the window opening. Prime the pinch weld (not a paint, but an adhesive promoter). Place a bead of urethane around the pinch weld (about 1/4" thick bead). Place window in opening. Duct tape it so it stays. Go back inside and put any hold down strap back. Roll side windows down and slowly close doors. Wait 4 hours to dry.

Or just take it to a auto glass shop. May be easier and cheaper that way.
