I just sent a set of upper arms for an old BYC order to Josh Lilly in Louisiana.
Im looking into how well they fit. They should be great but its been a while since I made any of these.
As soon as I finish another set I owe Ben in Australia I will post pics and details here.
Ben if you are on this list, you are next up. I have all the plates cut, drilled and all I have to do is make the crossbars.
