Looking for a way to put carpet in my tow vehicle, its a custom stretch of a 95 gmc 3500hd, Monroe truck made it into a crew cab from a knock down. The problem is the floor is totally different than other chevy crew cabs. Monroe made the floor and tunnel out of sheet, so a stock chevy carpet kit for a crew cab doesn't fit, So how do I do a custom carpet kit and get it to form to the tunnel ??? its the last thing I have to do to have the body and interior done....
