an adjustable joint comprising a first body and a second body, wherein the first body and the second body are rigidly connectable at a selected contact angle to adjust a pitch of the second body,
wherein the first body comprises an adjustment surface and the second body comprises a contact surface, wherein the adjustment surface is disposed against the contact surface when the first body and the second body are rigidly connected, and wherein the adjustment surface is unitary and comprises first and second planar surfaces that are abutting, with the first planar surface being angled away from the second planar surface, whereby the first and second planar surfaces are non-planar,
wherein the first body further comprises:
at least a first adjustment aperture extending through the first planar surface, the first adjustment aperture being internally threaded; and
a first set screw disposed in the first adjustment aperture, and
