Do '65 Cuda Assembly Manuals exist ?

The assembly manual is not the same as the service manual. Having the service, parts, and assembly manuals will be of great benefit in reassembling this "basket case". The service and parts manuals are easy to find. The assembly manual, not so much. You might get in touch with Kevin McCabe ( kmccabe56@yahoo.com ). I am fairly sure he has the manual, though I don't know if he has it in a format available for sale. He can probably direct you if he can't help you.
