Thanks all! I feel silly, did not know they were one seal...That might tell you how dried and rotted those things are... and how little mechanical awareness I have.
I am a bit nervous, I purchased seals from autohaus.com, they are Uro... I will definitely have them installed by a pro hoping they can make it work.
Any advice if I should go with a mb shop or straight glass shop? Unfortunately I am on a budget and always trying to balance cost and quality...
Newbie or not, this is an important lesson to understand on any Mercedes:
ONLY BUY OEM RUBBER and ELECTRICAL PARTS!
Sorry to "shout", but as someone who has worked with a wide range of Mercedes chassis' cars, and dealt with such things as windshield and rear window seals, there is a difference in aftermarket and OEM parts such as these that the average DIY or MB owner will never notice - until they fail or leak.
As for URO brand, well, it's my opinion that they are some of the worst parts on the market. My favorite example is flex discs - a Lemforder (OE supplier to MB) flex disc might be $120. The equivalent URO part can be found for under $40. That's 2/3 of the price of the OE part. Would you trust it?
Rubber parts are very, very easy to cut corners on, as by just adding a higher percentage of lampblack (carbon) to the mix the part looks the same and even feels somewhat the same. However, what little virgin rubber is in the part will not matter when it starts to break down.
Seals are especially prone to failure, since they're exposed to the elements.
OE/OEM seals are very expensive. That being said, do you want to have to replace them in another 2-3 years or less? If you live in a harsh environment the breakdown of the part will be accelerated by sun and temperature.
First rule of MB preservation - always, always use MB or OE (if they can be had) rubber. You might not be able to get OEM seals for a model as old as yours, but you can always check with the Classic Center and see. If not, try to find the OE supplier and see if they make them.
Do NOT, however, buy anything branded by URO. I have heard rumors that some of the big parts distributors such as WorldPac are dropping URO, but it's only a rumor at this point.
