My meager attempt at a homemade A arm bushing tool.
Got a steel pipe coupler. These are normally used on the ends of 20' lengths of pipe for thread protection. Around here, only malleable iron couplers are used operationally.
I clamped it in my Drill / Mill and cut a notch for clearance. You don't need a mill, you can do this with a hacksaw, as it's not critical
The bolt is a scrap of 1/2" allthread.
I bought some (called locally) "flat plate washers." These are not only very large OD, like a fender washer, they are thick as can be, maybe 3/16" ? "I used two" LOL
I could've gotten the new ones in, but the arms really should be cleaned up
