Nope. I know the build sheet is usually buried under carpet, or into seat springs. I've even found them in door panels and behind kick panel or sail panel trim. Full-size vans used to frequently get them stuffed above the fiberboard headliner. I know that even the later cars have more data on the build sheet than the RPO label, right down to trim, correct axle code (many RPO labels are NOT, incidentally), and items not normally found on RPO and dealer order sheets.
I meant the RPO label that replaced the metal trim tag that used to rivet to the firewall or door jamb. 'F cars had a plastic RPO label at least by 1982. 'P' cars had them in '83. I can't find either the tag nor the label. Then again, I can't find the A.I.R. pump, diverter valve, secondary air baffle on the E4ME, plug wire clip ring, half the VECI label, radiator splash aprons, A/C pressure cutout wiring etc. Looks like I have a real project trying to recover from a few years of neglect of a previous owner.
Thanks for the replies.
