In the second picture, I believe the loop on the right side of the photo goes around the jack handle and the loop & finger on the left side goes into the ratchet on the mast.
What I know of the only different between a 65 and a 66 spring is the way it attach to the jack. The lowerbloop wss the same aroung the bar. Can the old style spring been used with the 64 and 65 jacks but somewhere during 65 production they changrd?
This card on the inside of the glove box door, are those rivets repopped somewhere? I've never seen nos ones!
