G'day , yes i have just taken 3 to show you . It has been sitting outside for some years so pardon it's condition . It is drilled for 5 stud F100 and 6 stud Toyota , you will always have 4 Siamese holes doing this . It would need to be heavier for a tractor . The hole is for the rope , simply push it into the hole 6 inches , wrap around the drum two times and it stays in place with no clamps . The rope/strap must be wound so that it exits the drum from the bottom , it MUST be passed through a pulley block and back to the opposite drum . It will pull as much as a 4X4 can twist in low range which is plenty . You leave the vehicle in 2X4 so that the vehicle does not get traction and over run the winches causing slack cable . You could even make a pair using old wheel rims .
