I didnt think so either but one of my mates is trying to buy a Falcon off a guy who has told him that the jedi ball and ramp struts were replacement parts in the 60's - I told him it sounded like a crock but I would check up first
On the back of many kenner instructions you will find a kenner satisfaction note. I know of people who reponded due to missing parts and received them in the mail in baggies. I have also seen some on Ebay on occasion....as far as them being from the 60's...someone may be smokin crack.
