If I want to install replacement carpet in the NSX and the carpet (Wilton Wool) comes 36" wide, how many total yards would be needed to replace all OEM pieces? What's the length of the longest piece? I assume it's the two pieces that run under the seat from the dash to the rear bulkhead? Just trying to get an idea how much material I'll need without having to remove the seats to do some precise measurements. TIA!
