Most mustang parts vendors have available a small 2 page paper book(
printed by Osborn Reproductions) that list all the factory and dealer
options for each year. I think they run about 5.95 retail. Also you need to
know that ford options came 2 ways. RPO or regular productions options, were
factory installed options. DIO or dealer installed options were installed or
availalbe at dealers. Some of the options could be had either way. Ford also
had a factory muscle parts program availalbe in the mid sixties. Many
options not listed for the mustang were installed by dealers prior to first
sale and the arguments at national shows have raged for years, about what is
"original" equipment.
