early Mustang convertible accessories 19641/2 documented

I am seeking info that will document accessories for my 19641/2
mustang convertible. I know many were add-ons at the dealer
thanks  for the source  

You may consider purchasing a 1965 Mustang facts book, which
 should be available from any Mustang parts vendor.  It will have
 a list of options that could be either regular production
 options/accessories or dealer installed options/accessories. It
 may be difficult to document if they were dealer installed,unless
 you have the original paper work from the dealer that they were
 installed after delivery.  I hope that this helps  

Are you wanting to know when a particular accesserie became available through Ford, if so give me a list of what options , I have every shop tips article, accesserie pamphlets and almost all factory options books, which have the dates of availabilty.
