Hello, my sunroof drain leaked and damaged my headliner. I just took the headliner out and was going to clean the rear drains. I read that there was somekind of recomended maintenance for the drains, where you would put some kind of sleeves at the rear of the drains so they would not kink. Any advice on how to best access them? With the headliner off it looks like the drains run to the trunk where I will take a look around today.

More importantly, my headliner was the kind that was cut away in the middle for the sunroof mechanism. There is a huge rectangle cut out and the headliner board is almost like a frame. I can not find information online on how to replace the fabric on these since it is not just a solid board. Anybody know anything?

Thanks!
