Hi, What lower tall ball joint is being used with the B spindles on an 87 elco.I have not found the correct one yet. Moog k6117? Can't find a parts store that stocks 1 so i can measure the lower housing to see if it can be turned down to fit?? The auto zone ones are cheap crap and are smaller diamater, They also have 3 different ones that cross over tok6117 but are not right?? HELP!
