Thanks for the pictures LeeJohn
I have seen these type of hinges on new dump trailer like Carry On, Iron Panther. My trouble is I have check with a few hardware stores to see if they may have pre-drill square washer with at least 3/8" thich or more. But none of them seem to carry any thing this heavy. Perhap I haven't talk to the right source yet. My trailer plan is on order hoping in it will sugguest where hardware source's are or in worst case I may have to fabricate them out of raw metal plate
