A lot of my old pictures are gone because of my site crash a while back. Only pictures I have o f my arms is after powdercoat. But I have these from when I did the Nissan.
Its not a difficult modification. If you don't think you can do it, I have a JIG set up, and I charge the cost of materials to do it. I have a set of stock arms here that I just swap out when someone wants them done, so there isn't a big wait.
