I see no problem with welding a hard face weld on the angle lever and then grinding to proper dimensions, A skilled welder could do this.
You also may want to check the adjustment of the angle lever cam # 49/49U which can be bent in or out to align the primer slide so that it
doesn't bottom out with force against the coluum shaft causeing extra wear on the angle lever cam.
If You decide that a new angle lever is needed I have a new one that I could spare, If so, leave me a PM on this forum or send me an Email.
Good shooting
