My truck has an aftermarket control arm lowering kit whose manufacturer I cannot identify. (I think it is Western Chassis but there are no part numbers on it) It needs a new lower ball joint and the stock GM replacement will not fit (bolt holes set up different than stock). I cannot get any of the aftermarket "tech support" people at Belltech, Western Chassis, etc. to help me I.D. the correct replacement ball joint and NAPA and the parts stores no longer have the hard copy references anymore to just look up the bolt patterns and match it to a part (highly frustrating as I have been looking for a couple of weeks and driving on a metal to metal ball joint, ouch!) Can anyone out there help me or point me to a resource to I.D. the ball joint? It looks just like the stock one but the bolts are 1.5 inches apart (close ones) and 3.25 inches apart (the wider ones). Thanks!

 

You may have to start by going to a junkyard and getting a pair of lower control arms with the O.E.M. LBJs still attached...

Once they're on the truck, you'll be able to spank the LBJs at your convenience, when/if they go bad.
