Bill, I have no idea what arm this is. Can end, purple color on one pole, white color on another.
Fine lams. The big balance holes were there when I found it. The 2 little tiny holes were drilled by Hershman.
I know one thing, Hershman checks your stuff to make sure it's worth working on, and billing you for, before he spends time on it
So I knew it had potential before I started.
One thing about Cucarachas, if the motor isn't right, or blows up , it takes less than a minute to replace it
