i broke a lower ball joint and was wondering if the full set of a arms left top and bottom and right top an bottm off a 1999 will bolt onto my 1988 they look the same but not sure wondering if anybody knows before i go buy them

 

I don't think they will work. Not sure why they won't, but I ordered an aftermarket set of a-arms for my '97 Warrior a few years ago and they said the arms for the 90-04 would not fit 87-89 Warriors, and all the manufacturers said the same thing.
