these lower a-arms are aftermarket( i won't say whose). ordered them for 03 mxz, got a call day of reciet and was told ball joint cups were welded on upside down. they were sending new ones and throw wrong ones away. couldn't bring myself to chuck 'em. if you want to cut 'em up and weld them up right could be an cheap fix. probably sell them pretty cheap. pm me if interested.
