My car has been in storage for many years and mice found my carpet to be a perfect litter box. It has to be ripped out and replaced down to the floor pan. Where are some good places to purchase quality carpet for an '89 Firebird?

I don't need a new headliner but I'm afraid it has picked up the smell of mouse poop and urine. I'm going to see how well Lysol can clean up the smell but if I'm not successful where is a good place to purchase new headliners?

Thanks!
