In my current configuration, the pin is bolted to the bracket with 5 bolts. It appears that if I were to raise it, I’d lose a bolt and have 4. Anyone using a 4 bolt attachment?
Try to find the model number. Normally stamped somewhere on box. You have a prety big rig in profile. I would be thinking at least five grade 8 bolts at a minimum. New rig, I would call the factory or if you trust dealer call them.
