I do agree partly with post #8 (68 Charger) but my only issue is, on the lower cowl (windshield trim) you cannot measure the length of a curved area of trim, by placing them side by side. There will be one piece of trim longer than the other, because of distance. You have to place them one on top of the other, to get the overall distance, (length). I have sold a many of cowl top's and bottoms, off of 4dr sedan's, at Carlisle, with no issue's, to people, installing these on 2dr cars. Just trying to find out, where the distance difference is in the lower cowl trim as described in post number #8. Please let me understand further. My brother and I are friends with (MoparMark) in Colorado, and he has seen our drilled sheetmetal, at Chryslers at Carlisle, and we have had a few conversations about any differences in cowl tops & bottoms, and we came to the same conclusions, that there is no differences. I am not here to argue, just trying to help when we can, and to be a good B-bodies member. Have a great day everybody! Dodge33
