This is correct. I really would like my '73 to look like that, I just have to find the flares and an air dam to suit.
I have a fiberglass mold for a Datsun 510 air dam so that I can make another air dam for my 510 if I break mine. I was in the process of fabricating a lawn-edging air dam for my '75 Hilux but I held the 510 air dam up to it and it looks like it is a very good fit. It wouldn't happen soon but maybe over the winter I'll have some air dams made from the mold. I am definitely going that route rather than sectioning anything to fit. I'll see if i can post up a pic of the piece.
