3 point hitch

I snapped some pics as I was fabricating a 3 point hitch hitch for my newest rebuild a 420 John Deere L&G tractor. I want to pull a 10 or 12 inch plow and need this hitch to do so. All hot rolled steel, 1/2“ lower brackets and lower lift arms. 3/8“ yokes and lifting brackets. 1/4“ center lift are. I used the stock rock shaft for the 3pt lifting arms.
