Need new seatbelt(s)
 

My passenger's side seatbelt is stuck and I need to replace it:

It seems that seat belts are quite hard to find online, does anyone have a good source?
Quick poll:
a) If the passenger's side seatbelt is broken, shoudl I replace the driver's as well?
b) And if the answer is yes, in a different color (Red or yellow)?
Did anyone buy colored seatbelts and has a good source for it?

Thanks

Stuck? Pull really hard and it might fix it. I had it stick on me once but it took several minutes of fury to get it unstuck. Been fine ever since.

i tried everything.
I even took the damn thing apart and the car "rewarded" me with a steady "check airbag light" :-(

and the end of the story ...

Just for reference purposes I am answering my own question:
I called Suncoast. And as usual their price was much cheaper than buying the seatbelt from Porsche
HOWEVER: A seatbelt is "hazardous material" (due to the explosive charge for the seatbelt tensioner), so the shipping charge is around $50, which now made it a wash.
So I just picked up a new seatbelt at my local Porsche dealer ...

It's not a warranty item? I though these things were covered under warranty, and for a longer time period than the rest of the car. Maybe I am wrong.
