The Curt Weight Distribution Shank part # 17120 uses the industry standard 3/4" diameter holes which are spaced 1-1/4" center to center. The bolts which are used to secure the head to the shank are also 3/4" diameter. If you need these as well you can obtain them with the Replacement Bolt Kit for Curt Weight Distribution Systems part # C17076 which has two 3/4"-10 x 4-1/2" hex bolts.
