I have a bar on my front doors too. I saw how the clip works to free the bar. I priced the weaterstripping at the dealer this morning when I went to buy oil filters. They quoted 155 Canadian. I am going to check the partsshop and see what they sell it for, as I am not in a hurry (don't need it today).
