I ordered my PHS docs last week. There is a code stamped on the plate on the engine cowl that shows it had the rally stripe, which I have found is not the HO stripe. I think is was a $40 option back then. I've seen a picture of another firebird with it and it just goes between the wheel wells. Thanks for all the info. And I will try and not put the stripe on crooked :-)
