babayjames has it right. You have to remove the panel to fit the new rear seal. The front seal is a *****. Don't go there if you don't need to.

well, it is all cracked and leaking, not to mention it allows the roof to hit the opening, causing rust along the edge of both the sunroof and the opening. I have already pulled out the front seal, and I am going to sand the rust off and spray some primer down before putting the new seal back on. the old one looks like it was glued in, should I glue the new one in too?

front sunroof seal - I am curious also, for my 1984, I have ordered 3 brands; Meyle, CRP and OE from the dealer. The dealer one fits the best but still is not staying in the groove around the middle. I even took the wind deflector and plastic holding clips out. I have strecthed it to try to help get in the grooves, but it is still floopy in the middle. Sunroof stays closed against it to help mold it in place. May end up glueing...what glue? 3M or black windshield sealant?

mercedesource.com has a sunroof booklet I may end up getting to see if they shed any light on this front seal.

The one front seal I did was a Meyle. It took all I had to shove it in- no glue. Its hard to figure out just how it is supposed to be oriented. It's still too fat and the roof doesn't close on it properly.

I got MB Star seals from phil.
they look pretty good to me, but we shall see.

I hope this makes sense; on the front edge of the front sunroof seal (closest to hood) there is a dip (ridge) in the rubber that gets hooked or pushed into a groove (slot) on the metal holding frame under neath the roof (it is hard to see). The back end of the sunroof seal (closest to the trunk) has a dip (ridge made into it that hooks and holds onto another groove or slot. The curved parts near the side brushes did the above and fit nicely, but the flimsy part in the middle I can not get like that. I even tried starting in the middle, tried some lube also, did not help. May end up glueing with some 3M eventually.

For the rear seal; remove sunroof headliner, pull the clip on the rod and 2 bolts 12" near. Then pull the sunroof out just enough to acess rear seal. On mine, it fit in the grooves nicely. I did have to cut and glue (3M) at the curved part so it would not come loose.
