Bob, for the sake of arguement, (I had little space up there) let's assume the term (in the original position) was part of the choice. In other words, if the car uses them in the front, but not the back, then it's non RRs at the back, but RRs are Ok in the front.

Sorry that wasn't clear earlier. if anyone wants to change their vote, contact me.

(Also, I'm trying to get a feel for the crowd on this...it's just me thinking out loud. No official action or poll is being taken! )
