70 swinger dist. blocks etc

I think I just figured this out....from staring at these blocks for the last hour....the texas shaped rear valve is built into my original front inner fender valve. so dur I got the wrong front valve. I need to get the same as what I have and return these two other new valves.

correct me if i'm wrong...but all I need is this part.

except I don't have other little valve on my car...am I supposed to have that?? the one with the little black rubber boot in the ebay ad.
