1975, in F-series trucks with the 240 and 300 six. About the same year as the crossover from points ignition to DuraSpark electronic, if I'm not mistaken.

The 240 was discontinued after the 1974 model year.
First year of Duraspark-I was mid to late 1974 models.
1975 seems right for the EGR Valve, with a couple of years earlier for california.
