Astroroof vs dealer installed headliner question

[Phoneguy]

I have a dealer installed moonroof and will need the headliner replaced. Will a factory astroroof headliner fit? The reason I ask is that the slider part on mine is metal and I would like to replace it with the factory style. Is the roof the same size? Anyone have some measurements for the factory installed size and placement?
Obviously the dealer installed unit uses the standard hardtop headliner, and it fits like crap. Anyone have a better solution or do I get a custom headliner?

Thanks
