I recently just purchased a new headliner from Hawks and I am sure I can replace it. But I am not sure about the A Pillar. How do I remove it without breaking the clips?

 

Not sure, I did pick up a 3 pack of clips for $3 at Advance auto. Dorman PN 963-040

 

You're talking about the ones that run down the windshield? Good luck. I removed mine today and broke all four of them since theyre so brittle.
You'd be better off grabbing these and being able to replace all of them in your car :

If you ever replace door panels I'm sure you'll break some doing that swap too

 

Well. That sucks because I was really hoping I wouldnt have to buy any, If anyone else knows any tricks they would be much appreciated.

 

you can still get all the clips from Napa
