Since unleaded fuel was not even generally available until '73, although there was a brief period of "low lead" fuel before that, which would still fry a cat. Anyway, not even special emissions California requires a Smog on a '75 or older anything, car or truck. I think the first emission devices were EGRs in '69, airpumps started in '73 and cats started in '75 and I think had to be on all passenger cars in '76.
