After changing my head gaskets, and every other gasket and seal on my way on my 3.9 '88 Dak I noticed my throttle rod was loose and just sort of hanging and upon checking it the ball on the lever is so worn the swivel pops off with the slightest bit of force, and after reading and re-reading parts manuals and my repair manual I can't actually find a part number, or even the proper name for it, is this replaceable or can I buy bushings as a temporary fix? Sorry to be such a noob. I've had quite a time between starting college and a head gasket failure.
