Most pintle hooks use a standard bolt pattern which is 3-3/8" horizontally center to center and 1-3/4" vertically center to center (see photo). Therefore, the Pintle Hook part # C48231 would be a direct fit and work well for you. It also comes with all the mounting hardware needed for installation.

I have attached a review video of the above hook for you as well.
