I recently purchased a 2019 Dodge Grand Caravan GT and discovered the bolts to mount a trailer hitch are missing. I read that I need M12 bolts with a size of 10.9, M12-1.75 x 2 inches, but the install directions from Curl mention an M10. Can anyone help identify the correct size for the M10 bolts?

Edit: The dealership offered no help and requires an OEM part number.

Thanks!!
