62' c10 floor carpet needed

[Bullett]

Doing some work on the ole gal this winter, floor carpet is going to be replaced. Has anyone bought a carpet from jc Whitney? I am going to order my precision weather strips from them and figured the carpet at the same time. Has anyone ordered a carpet from them and if so, we're you happy with it. Also, I am a little confused about "tunnel height". They have a 3" tunnel height carpet and a 7" height? My tunnel isn't exactly either. It starts out maybe a couple inches at the base of the seat and tapers to 4 or 5 inches towards the firewall. Is this considered a 3" tunnel? Thanks...
