I checked RockAuto, and it seems that the first relay I posted was used from 1979 - 1984.
The other style in the second picture was used from 1985 and up. I am not sure why the design was changed, but since my truck has a carburetor and Duraspark ignition, it should work fine on my truck.
Handling both of these relays, I can tell you that the one in the first picture (older style) is a bit heavier and more solid than the newer style.
Watch out for some of the newer models. At some point they did away with the "I" terminal. I think it was an 86 Ranger I was working on had that newer style.
