several joint descriptions state 35* for a single joint, but there are double joints out there from several companies that allow more angle. unfortunately, i can't at this minute, state what the maximum angle is for the double joints are. the "oversize" 3/4" heim measures .757 ID. using a common 3/4" heim won't work on a bare 3/4" shaft [even if it measures a common .749 OD. size], and any paint makes it even worse. [can't think of anything being worse than not fitting in the first place]
