Alright, after looking forever for a replacement for the cloudy rear window of my SDL at the local JYs (and breaking one trying to remove it :(), I finally pulled a really nice one last weekend. Now all that's left is to install it.
(I replaced a W123 front windshield myself some 25 years ago and it wasn't too bad but that was with my brother and dad around to help...)

So I decided to have one of the local glass guys do it for me; they estimated about 2 - 3h and $150 for the job. Not necessarily cheap but if they do it right I'd be OK with it. The only question left is whether I should also replace the seal or not. Initially I was planning to ($144 at the local MB stealer) but the glass folks would prefer to reuse the old one since it seems to be in good shape (according to them) and a new seal apparently increases their labor cost due to removing and reinstalling the aluminum trim. They also raised some concerns about bending the trim when installing it into a new seal, which didn't exactly give me the warm and fuzzy either.

So, is the trim a real issue? When I pulled the glass at the JY I removed the trim, just to see how hard it is to get it off without bending it. It actually wasn't a problem at all but I can't speak for installing it with a new seal.

Thoughts?

Thanks

i'd replace the seal. $144 seems steep. i'd make sure they are a good shop too. i had my windshield replaced on a '94 firebird, it was $400 and they did a terrible job. the windshield has shifted down towards the hood. thank god it's a POS, but a v8 with 206k on it! i feel like i have a record breaking pontiac v8 in my garage:D to bad they're out of business i could be on a commercial:cool:

The seals do cost that much. If it were me i'd want a new seal too really as thats the cause of cloudiness in the first place.

First put the seal on the glass and then fix the chrome trim into the seal. This way it won´t be bent.

Thanks guys...

Hmm, interesting, I just picked up my C2S from the independent guy that does all the work on my cars that I don't (want to) do myself... Asked him for a recommendation on a good glass guy. He came up with 2 shops; so I called one of them and same answer: reuse the old seal.

Still leaning towards replacement though, just not in the mood to have this done twice in case the old one is bad.

I had a front windscreen seal reused on my little Citroen and it leaked like a sieve after. Absolutely poured in, had to put in loads of sealant. Different kind of car tho.

I've got to replace both the front and rear screen :(

The front has a small chip and the rear's defrost element is burnt out. And we don't have JYs for this stuff.

Maybe this ship has already sailed for you but don't count yourself and a buddy out to do this job. I have never replaced a window before period and by searching and reading this forum, I was able to get it done in a few hours on a Saturday morning. Has been perfect since. Here is a link to my post. Not a lot of tips or anything, but some pics of the process.

I put the trim back into the channel on the seal before I put the window back in. All in all, the job was a challenge but by no means difficult. My buddy had never done this before either. Maybe I just got lucky. I just took my time, was very careful about not exerting too much pressure against the glass, and just roped it in. Good luck.
