After looking very carefully through my database,
I believe the following to be correct for 71s:

GTX
N96 - V21 blackout was standard
non N96 - V21 pinstripes were standard but could be omitted

Road Runner
N96 - V21 blackout was optional (and included in A87)
non N96 - V21 pinstripes were only available with A87

addict:to devote or surrender (oneself) to something habitually or obsessively ....hmmmm
