So, here's my question. I have a 1980 Caprice (technically the wrong forum I know) Which I have built up with 350hp small block, TH350, posi 8.5" 10 bolt etc etc etc. I have a rear roll bar so I know it's a genuine F41 car BUT. I really want to know what other RPO's were factory on it, I have looked for a build sheet everywhere. It's not visable under the front seats, it wasnt under the rear bench, wasnt under the dash pad, wasnt under the headliner, not under the carpets front or rear.... Is there anywhere it could still be lurking?? I have ALL the history on the car, service book with VIN stickers still stapled to it (service info sticker missing) even the bill of sale with dealer options listed. BUT NO STUPID BUILD SHEET! If I cant find it can I get this info anywhere else? It's a 1980 so dont say check the glove box as its not got the SPID service info in there (pre 84 dark age car) Any ideas??
