I could not find any site that has them all in one place. The federal archives on-line do not appear to go back that far either. Perhaps you can contact them at the site below and they can send it to you.
http://www.archives.gov/federal_register/a..._and_hours.htmlDid you try entering the volume and number in Google (e.g., "Federal Register, Vol. 53, No. xxx") and seeing if there were any specific sites out there that have just the one you are looking for?
