I thought the interior sweep from a cutlass along with the upper metal cap of the upper door panel would work. It does work but the contour of the cap is not the same as the rounded cap of the GP so it doesn't match the door pillar trim. So I figured I'll just buy new ones burt the GP parts are hard to find and I can't find just the interior sweeps. I did come across the listing for them were the same as a Monte Carlo. I found some interior sweeps at Dixie Restoration and the price is really good so I called them to make sure if it would fit my GP. I actually spoke to a human who asked if the door panel was straight or curved. The GP is straight so he said it should fit. Nice to talk with someone who actually knew about the product and didn't give the answer that others would give from a line of the "how to respond instructions"......
