I just installed the one I bought at SC and itfitsperfect I would highly recommend it
For what is worth. I have a 73 sport that I believe is a 1 piece. It has a metal hold down strip that runs across the floor right behind the front seats. It also has the metal trim hold down strips that run from the front of the cab section all the way back to the rear hold down metal strip.
Being in California I like the mat set up.
I do need a new front section and would like it to go under my front seats.
It's too bad that a mat is not offered as such.
