2 ft Long Chain Link Fence Post Extenders for 2" (1 7/8" OD) Fence Posts (Pack of 5)

I'd set posts in the 3 longer bays and swap those barb arms on the corners to them. Spike these new posts into the dirt a bit with a hammer into the freshly dug hole to set sturdy accurate height then fill in around with concrete. Buy 6 post extensions at 1' each for every corner then buy the brace bands for each for the barb wire connections. Put on bulldog hinges instead and swap all the tension bands to be correct.https://a.co/d/04dS8ejh Something like these. Sit right on top but you'll have to find black ones or paint/powdercoat
