How does the trunk divider install

@macman340 , are you positive that your convertible had a seat divider? Due to the fact that the top has to collapse into the "well" between the back seat and the trunk compartment, no seat divider was used for the cars that I am most familiar with.

My other 66 dart convertible had a small seat divider attached to the back of the seat with the Boot rail and 2 screws on the sides. about 10"tall and 40" wide with the cutouts for the hooks.I'm going to use 1/4 plywood sealed or .125 ABS as a replacement part.
