Like I said, I meant no offense, but obviously we're on the same page about the bar on the back. I'm not sure why I noticed the reason for the bar in front being that on the back would interfere with the clevis's, then immediately welded plates that will interfere with them!
Anyway as someone else stated, the way to go would be to just build them all from 3/16ths. (5mm). Hindsight......well you know.
Well I also got much better @ welding galvenized! : P
Also was nice change back to heavy plate!(I'm a heavy truck mechanic/fabricator)
All painted up with bushing installed. We'll see how paint holds up to Oregon coast, its Valspar Tractor Emplement paint.
