Bushings here. OD is measuring about 1.395 which is perfect. Just need to cut some "eye" at 1.65" and build some links.
Bought lol. I work for an industrial steel fabricator. I just pay wholesale for steel, or sneak some parts in the fall off peices we burn for jobs.even the tightest nest leave lil spots I can stick a gusset before the drop goes in the scrap bin.Pre-made gussets can be bought easily too
