Please help me figure out my cars invoice,

[YenkoChevelle69]

OK, here goes. I have a 69 Chevelle 307 glide car with a 10 bolt. In all honesty nothing more than a bonified parts car due to the rust. But I really want to hsave her due to the 3 inches of paper work that came in the glove box. POP invoice, order form. I am sure the build sheet is behind the seat still. I am a bit leary of posting a picture of my invoice due to all the duplicated tags and what not going around. IT says P. Glide. P. Steering, V. Roof, V. Int, W/Discs, W/ Sidewalls, P.B. Radio. I didn't think malibus could get the disc option. I have no disc brakes and talked to the original owner (Me being the second) and he said that he ordered discs but did not get them. Did GM screw up when it was ordered? B/C when he recieved it (6/6/69) it was a manual drum car. ORiginal owner has since died. (March 15, 2002) So I cannot ask him anything else. So I have 3 inches of upkeep papers that have a story to tell. Please Please help me. I am about to pull my hair out b.c no one seems to know the answer. Thanks in advance.
