Went and looked at my unmolested 58 trunk.
I am assuming that they supplied you with tan push buttons.
Facing the trunk from the rear.
Left side is held in place with 6 buttons.
rear left side is held in place with 7 buttons and just noticed that in the upper out side top is held in place with a chrome screw.
rear right side is the same as the left. Screw is still present.
right side is held in place with 5 buttons.
I forgot camera but will take a few pics tommorrow and have Ray post.
Sun Prairie, Wi.
Here are the pix that Fuz sent me. Thanks, Fuz! Dennis, I am gonna forward Fuz's email to you because they are much bigger pix than I was able to post here. You should be able to see the buttons a lot better.
