66 Olds 98 pitman arm to relay rod connection

[RileyWatervilleOlds]

Hello. I am new and would appreciate any help. I have verified the slop in my steering is at the pitman arm to relay rod connection. I was able to purchase a pitman arm but it does not include the part that connects
it to the relay rod. I have talked to a NAPA store and they were stumped, as was my mechanic. Thanks for your help. Mike
