Right there in the link I provided above...here's direct link to the valve for sale on the same site:

Again this ASSUMES your car was actually equipped with it...for disc/drums. I guess I sorta made that assumption because you purchased 2 piece line, which would normally be for disc/drums I believe...and would need the valve

We still don't know if you're asking about a drum/drum or disc/drum car.
