70 GTO RPO codes question

[Supercar_Kid]

Oops...thanks again Don. This Pontiac stuff is a little thinking outside of the box for me. I'm still a little confused about the tires. Obviously it came with G-70 14" white stripe Firestones when it was new...as the original is in the trunk, but the PHS docs came back saying PK2 G78X14 WW Fiberglass tires. They even typed up the repro window sticker showing the $30.54 upcharge? Is this a mistranslation or something, was it simply an upcharge to specify the whitewall on a GTO, and a Tempest would have wore G-78s or is there more to it than that? The original tire pressure decal in the glovebox shows both, but appears to be a generic Tempest GTO design.
