70 GTO RPO codes question

[Supercar_Kid]

Thanks guys. Like I said I don't have a ton of knowledge about Pontiacs so I appreciate your help sorting this stuff out. The car is cool...unfortunately it's not mine but a friend's. He picked it up off the original owner just a few weeks ago. It's been a local car it's entire life and came with a pile of paper, bill of sale, warranty booklet, P-O-P etc. It's a Cardinal Red w/ white "Cordova" Top & red bucket seat interior, 48XXX miles, 455 M-21 wearing mostly original paint w/ some really interesting day 2 mods. I will post more pics later. You Poncho nuts will dig it for sure.
