Afternoon folks!

I have a water leak coming down the driver’s door post on my roadster (can see the split in the seal) so I asked my son who works for Honda to see if he could find one and came back with Chrysler wanting nearly £500 for this seal (it does go right across the roof and down both pillars, you know the one i mean... but still!) he did say that one of the chaps he spoke to mentioned that it’s the same seal that was used on Saab convertibles... now... having just parked near one and had a good look, it would seem to look very close but I was just wondering if anyone else has heard of this as i’ve had a good hunt through forums/internet etc and can find no mention and the Saab seal is only about £40 if it’s the same
Any help/input/knowledge would be much appreciated!
