Any other jobs while headlining off?

[Painted Pilgrim]

My headliner is peeling back at the B pillars and I've sourced a replacement.
I'm wondering if anything else should be checked or serviced while the headliner is off?
I know the hydralic system for the roof is up there and also the dreaded roof drains...
Any advise welcome please or indeed tips on removing the liner itself

Where do you source the headliner?

I did not check or served anything while it was of. Forgot to take a picture
Removing is easy. Youtube is your friend in this job as is the search on this forum. I have an older 2006 Cali. The rim that hold the headliner in the poptop was not rivited but hold in place with 4 screws on each side. I loosend the pillars, did not take it of all the way. The headliner in my case is very flexibel, not made of rigid plastic but is more like compressed PET fibers.
Take very good care with the frame of the controle unit. The plastic is brittle, tightening screws to hard can break it easy.
Good luck
