The rubber on the right side water deflector looked perfect before windshield replacement, but after they replaced windshield, the rubber is out of position at the rear end.
Is this usual, when the windshield is replace and old water deflector is re-used on W124?

One of the MB dealer I mentioned is dealing with this glass shop, but this glass shop did such a poor job on MB, and asked me to get parts myself.

That MB dealer has body shop a few miles away. That body shop deals with a different glass shop. This glass shop also asks me to get parts myself.

Will glass shop remove old clips and put new clip for water deflector without making scratch on paint? If they make deep scratch, rust will grow. (Indeed I found scratch on the edge of hood. I touched it up with MB touch up paint.)

Could you recommend a good body shop or glass shop that does the trim work on W124 well?

Dealer says they can do the water deflector work, but they say they send my car to glass shop for the rubber around back glass. Shall I have dealer do the water deflector job, though it is more expensive?

Is this DIY for novice?
I think 88-855 and 67-220 (in service CD) are the jobs I need.
Do I need to remove the glass to replace what they call rubber lip in 67-220?
