R230 Upper window seal fitment. Easy?

[roadster198]

Hi All,

I've been trying to trace a leak on my 2009 SL350 facelift. The rear window lower seal has been replaced and it appears to have fixed the common problem in that area. I've also messily fixed my LHS c-pillar seal. Yet I'm still getting water into the boot. The pictures show that the water appears to be dripping down from deep inside the roof mech

Looking at the seals in the upper window area both the sides are torn.

Has anyone replaced this seal? Starpartz have what I need.

It looks like a window out job and a bit of a job to remove and replace.

Has anyone done this job or paid to have it done?

any info appreciated.

Thanks
