Trunk prop question

He is correct there were 2 types of props and it changed some time during the years there is the ratchet type that my 65 barracuda has which is broke I have one found I just have to get with a member here when time allows and the spring loaded one which the spring after all these years has just gotten weak and won't hold the weight that's why I think they went to the ratchet type later. Ask around on here there are lots of members with this type of part stashed in the garage for a rainy day good luck.
