I used to be the driveline manager for a company in Memphis, I'd probably do a one piece, back when I was doing it, about six years ago it would cost you about $120 to $160 to build one using parts off of your old shaft. Your shop will need measurements from center cap to center cap of u-joints with your truck in ride postion, just in case the distance from your diff to transmission may have changed a little after the new four link.
