When they were used (not all 65 used the prop rod) they would be typically installed on the drivers side for the rod attachment. Passenger for the holding bolt.
Take a look at the pictures posted in the Unrestored Picture section of the site. Just checked and there are some there that would have answered your question
Looks like I've only posted one 65 example so far. Need to correct that but that one has two pictures showing the installation side for the rod.
