Trunk prop question

I had one that sagged like that and I added a spacer inside the tube to give the spring a little more compression. In my case I added about a 2" section of pipe or tubing....I can't remember which or exactly how long.....but a lot will depend on how bad yours is. You may need it a little longer or might be able to get away with a shorter one. The '64 and early '65 used the ratchet, late '65 and '66 used the "spear gun"!
