I installed it today and it was -- for the most part -- a simple job.
Pulling back the int. weather-striping was a little tedious and also lining up the retainer was a pain.

The only real hard part FOR ME was that my part had a bent wire, so I had to try my best (in 30 degree weather) to re position the wire to make it flush. I'll just have to...uh...work on it...

Overall it looks nice and hopefully fixes my leak issue. I'll test it out in 2 days when the sealant cures.
