Replacing the complete trunk floor panel of a 67 Convertible Camaro with a 68 trunk floor panel
This is no simple task, many things need to be considered. Here are a few of them.
What are the differences between the 67 and 68 full trunk panel?
What needs to be removed in order to insert the trunk panel in the car?
Will there need to be modifications?
Here is the 67 Convertible Camaro we will be working with:
1. First what are the differences between the 67 and 68 full trunk panel?
In 1967 Camaros were equipped with a single leaf setup "monoleaf", and non-staggered shock towers, this caused axle wind-up and wheel hop during rapid acceleration.
In 1968 to remedy the wheel hop problem, the Camaro received multi-leaf spring packs and a staggered shock layout as seen in the picture above.
As we will see later on we will have to do some modifications to accommodate this new layout
2. What needs to be removed in order to insert the trunk floor panel in the car?
In order to have better access and also to get a better view, we partially removed the left and right quarter panels as shown in the picture below
Next the rear seat brace has to be carefully removed, by drilling all the spot welds as shown below
After removing the rear seat brace this revealed rust that was not removed even after being sandblasted, this is not an issue anymore as the complete trunk floor panel will be removed.
Next the trunk floor panel is removed. To remove the trunk floor panel the spot welds to the tail end panel and the inner rear wheelhouses must be drilled. As shown in the next picture.
In our case we will not be removing the right and left edges (attached to trunk drops) of the trunk floor panel.
We are keeping these for two reasons, on the convertible camaro on the underside of the trunk panel there is a small panel that is not available on the new panel as shown in the next pictures.
Cutting the right and left edges of the trunk panel will also allow us to slide it in the trunk opening, thus avoiding to remove one of the frame rails and both the inner and outer wheelhouse on one side of the car in order to insert the trunk panel. Doing it this way will also insure we keep the geometry of the car intact.
Then both trunk hinges will have to be removed to allow the trunk panel to slide in through the trunk opening, and the trunk latch support also to give it enough space to fall into place
Here is what it looks like when all is removed and ready to receive the new complete trunk floor panel with staggered shock towers
In the pictures above you can still see the trunk latch support, but keep in mind it has to be removed for the trunk floor panel to fall in place
Here are some pictures showing the final positioning of the complete trunk floor panel
3. Will there need to be modifications?
The first obvious modification is when we re-insert the rear seat brace it will have to be modified to fit the new trunk floor panel
The rear seat brace will have to be modified to fit the new staggered positions of the shock towers as shown in the pictures below
The rear seat brace will also need to be modified in the middle as it goes right over a new design in the new trunk floor panel, in the position marked by the yellow tape
Well that is it for now, come back later as we will show you the modifications we made. Then we close up the back of the car with new inner and outer wheelhouse panels, trunk drops, and new quarter panels.
