Hi johnk,
I too bought URO door seals for my Pagoda restoration. The passenger seal (right side for me) works fine.
The driver's door seal has never allowed the door to close correctly. I feels stiff after just a little compression. Maybe the door was not quite hung right but I've never been able to make it better. It can only be closed completely (latched) with the door "stand-off" still 1/4 inch from flush in the back near the striker. The only way I could get the door flush with the rear fender was to completely remove the door seal. A note of interest is that, even with the seal removed, my first door-to-car contact point is between the metal lower door panel trim piece (groove that the door panel sits in) and the lower inner chrome trim that covers the wiring harness that runs to the rear of the car from under the driver's foot well. That first contact point occurs at an exactly flush condition between the door skin and the rear fender. In other words, the door thickness is exactly the same as the depth of the door opening in the body.
I bought a driver's door seal from the SLS-hh.de website in Germany but have not yet installed it. They offer two different seal qualities. I bought the more expensive one. I'm still removing 3M door seal adhesive to give myself the best chance of success when I install the new seal. The new seal is not an MB seal, according to SLS. I'm not sure there is such a thing any more. It, according to SLS, is a German-made seal using the original MB seal molding tools and the original MB seal compound formula. It is definitely softer (to squeeze by hand) than is the URO seal that I removed. I'm sorry I cannot really help you until I install my new one, which will be a few days.
For me, the driver's door seal has been a real frustration since the completion of my restoration.
Good luck to you.
