A nice surprise! I found OY's build sheet! It was in the worst place possible, folded up right underneath the carpet where the driver would rest their left foot. It is not in perfect shape, but I was able to salvage it and most of it is legible. I did find out that OY was built on March 15th of '78. The date on the door sticker is weathered right where the build date is supposed to be, so now I finally know when it was built. I I managed to straighten the build sheet out, carefully clean it up and put it in a transparent sleeve so most of it is readable. I found out a few other things such as OY originally had a locking gas cap (J46) from the factory. I wonder what happened to it. It also had factory floor mats (C92) and was delivered with five gallons of gas (Y95). The AM/CB transceiver (R12) and power tri-band antenna (R47) are also factory original. It was built already "sold" (Y14) apparently. I wonder if it was specifically ordered by the original elderly woman owner. I also know from original sales paperwork that I received when I bought it, that it was sold new at Bill Berry Motors, in Canon City, Colorado.
