I got the carpet from
www.StockInteriors.com
They offered a molded carpet for coupes, but as far as I can tell -- the passenger section between a coupe and fastback is the same.
I don't believe they offer "headliner" carpet as I managed to buy an entire headliner from a fellow Zilvia member parting out their car. A few shots of "Febreeze" to remove any odors and it was good to go.
Installing was pretty straight forward, remove sun visors/rear view mirror/dome light, a/b/c-pillars and piece in the rear and it comes right out. Installation is the reverse of normal.
I now have an entire brown interior for sale if anyone's interested. Haha
