Hey Brent, what you are looking for is the usable width of the Coupler Pin part # 37201281 that you referenced which is 3 inches. This is the distance between the shoulder of the head of the clamp out to where the metal clip slips over the shank. This would certainly be more than the 1-7/8 inches that you need!
