Maybe I missed it but is the engine & drive-train original? Make a sheet up listing (similar to what Gary suggested with past owners) the engine trans and rear stampings and date codes along with critical components which both assist obtaining a good price and quick sale. Identify the carb, distributor, starter, and any other original parts that add value like shocks, original spare tire or tire jack (date code), etc.
That way you have both ownership history and car detail documented which many in tune buyers want to know.
