Quick Hitches Bushing rolled pin size?

[Herkypilot]

I recently bought a used Cat I QH which came with a set of adapter bushings but no rolled steel pins. I figured it would be easy to find pins at TSC, but they don't have any that big. other than the ones that come with a new set. I believe I can find the correct size at McMaster-Carr, I just need to know what size that is. I left my bushings up at my property last weekend so I don't have them in front of me to measure. Can someone provide me with the length & diameter of steel pins?

Thanks
