Bomber, what are you trying to do? Fix the emissions equipment on your '78 2F, or fix the emissions equipment on your '79 2F? Were you hoping that the '79 stuff would migrate over to the '78?
You probably need to bust out the emissions schematics from the Haynes manual and start comparing. You can use SOR's website to compare part year applicability.
