See the tables on pg4 (they need updating) and RatPatrol's list on page 8.
I found the Filo car for L/S=13.00
57 Chev 150 2dr wagon
3406/250=13.62
The 2dr post I had guessed is a better fit to class, but that's Filo in the picture in the T-T race against an identical L/S wagon. Filo's name is on the door.
