hey i just got a part from a store that sells on ebay. It is a lower right a arm. I was attempting to put it on when i noticed that it wasnt the same size as my other existing a arm. The part that holds the bushings is much shorter and the bolts dont even go all the way through the mounts. Did i just get sent the wrong part or is my '89 warrior different from the 2001 warrior? I don't know if i should send the part back or make it work with washers and the old bolts. can you experts please help?
