Two Questions

[SixPost]

1. The "outer boot" on the passengers side of my sun roof is separating in the middle. I see that the part is available for purchase online for around $45. Anyone have experience replacing on of these on a 6? Is it a reasonable DIY or should I defer to a professional?

2. My rear deck behind the rear seat headrests is installed incorrectly it appears. Looks like the deck material should be wedged under the air vent at the rear glass giving a finished appearance. Mine is sitting on top and looking less polished. Tried to get a pic, but its not an easy spot to get one given the angles from the inside and glare / reflections from the outside. Anyone have experience working in this area? Reasonable to DIY or is there too much involved to take a chance...

Any help is appreciated-
