trying to figure out who makes a lower control arm for my 97 yukon

[dantheman421]

Alright guys, i have been searching for hours for who makes a lower control arm (left & right) for my 97 yukon with stamped steel control arms. All the ones that i found on jegs/sumit are for 2wd. I have 4x4. I just got off the phone with a parts salesmen from a local part store and he told me its possible that its dealer only? Anyone know if this is true?
