They are "VERY" hard to find. I wanted to buy one when my Pittman arm wore out but the price was too steep so I sent it off to be rebuilt at Steer & Gear. I was so petrified that it would be lost in the mail so used Fed/Ex and every possible insurance, tracking available. After everything was done I ended up spending about $400.00 just to have my Pittman arm rebuilt. I'm so glad most of these parts are rebuildable. Nice purchase.
