This kit, manufactured by Spring Creek Outfitters, provides all the parts you'll need to convert a standard 2x4 into a rock-solid rack at an inexpensive price. You get everything to make ONE rack, including: two suction triangles, straps to attach to car, two eye pads and hardware.

Directions:

To construct your rack, you first have to decide what length 2x4 you will need. If you are going to be hauling two canoes, we would recommend using a 78" 2x4. If you are hauling only one canoe, use a 2x4 that is slightly larger than width of your vehicle.

Bolt the suction cup frames to the 2x4's so the cups are to the outside edges of your roof, by drilling a 3/8" hole (or a little bigger, if you want to remove it later - to allow for wood swelling).

Set the rack on the roof to see where to place the buckles to make sure they are pulling straight down and drill another slightly over 3/8" hole and bolt on the strap buckles. Then, place black eyepads on the ends of the 2x4's where you wish, and bolt them on. Black straps must be placed through the cab of vehicle by opening doors and then snugging down securely.

This includes hardware to make ONE rack.
