I am replacing my lower front control arms for the ford racing arms which are supposedly made to improved '96 specs.I did the 5 lug disc brake conversion using '94 spindles etc.There are two versions of the Ford racing arms;pre '94 and '94 up.Due to the brake upgrade work I had done,which one will work on my '89?I am thinking the pre 94 arms even though the longer ball joints from the '94 up would probably work so I could get rid of the .3" spacer.
