Willie, I'm working from memory (which my wife says is spotty at best). I believe you should have 4 attachment screws. Two will be in the front, as you've seen. The rear two are camouflaged as holddown screws for the oval shaped chrome perches. If you flip the trim over, there should be two "tongues" fastened to the underside. They correspond to brackets on the hump of the floor. Installation goes this way; slide the trim section back (towards the trunk area) until the tongues slide under the brackets and then install the long screw (1 per side) through the trim into the tongue in order to sandwich the bracket.
My concern for you is that I'm not sure you have the hump brackets. I don't know if the bracket was deleted on fixed seat cars.
