Steering coupler or Rag joint

[motornut]

I replaced mine last fall
when i ordered the part at first it seemed there was only one used
Dorman 31011
this puts my steering wheel out 180 or upside down
called and ordered the 31015.....wrong size

called dorman was told "they have never heard of this upside down before"
asked at a GM dealer "someone may have changed something"
before i turn my wheel around,is this normal?
