hellwig sway bars

I looked on summits website and for my 73 Duster it says I need the 5905 instead of the 5906, and for the rear it says I need 6903 instead of 6905 but from the picture they show it does not look like the new one. Does anyone know if it is the new one just a different number and a generic pic? I just wonder because all the others that are 182.69 don't have pics but the 6903 does.
