control arm bushings

Hello I have a 92 xj 4x4 I need to know if both bushing in the upper control arms are the same .Have been told there are diff and been told they are the same by more than one parts house.

just pressed all 4 uppers and all 4 lowers last week-- uppers were same and the lowers were same-- I too, went here and there trying to verify same. It seems that many parts houses are buying their info from a faulty data base.

Thanks I asked the one parts house was told one time there the same them later when started to order they were diff.Same with the front axle ujoints there are 3 diff ones I was told so have to pull the front down take the axle apart and take them the old joint too match up .drivers side is bad my 85 there was only one.It a DD so cant have it down long.
