Problem with replacement Idler Arm

It can be a biatch. 3 ilders out there, parts store computers have no clue. Buy all 3, take 3 back.

The one that originally belongs to his car is a K7042 and that is what he ordered. That shows to be the only option for his car. K7086 is the 73 up idler arm. 1967 was a one year only but right now I don't recall that part number.
