Got the carpet for my '56 from Stockinteriors.com and am very pleased. Got low hump molded carpet that goes all the way under my gas tank to the back wall of the cab. It helps to have a scapel (works better than a razor blade or retractable knife( and a nice new cheap all-purpose scissors when installing. A soldering iron works great for making the holes for attaching the seats, seat belt retractors, etc. (I have Tahoe center seats in my truck.)
