vortech pcv valve? HELP!!!!!!

I am balls deep in my vortech install right now and have come to the part where it tells me to install the vortech supplied pcv valve:shrug:. I bought this kit used and did not get the pcv nor did I even know i needed it. what is the difference between mine and the one vortech supplies? can i run the car with my stock one installed? should i just keep the car out of boost till i can order one from vortech? please help. thanks. the car is a 03gt fyi.
 
I thought the PCV they use is off of a Mercury or something.

I can't verify that this is the correct one, but if it's NOT for a 03 GT and it is for another model then it's correct

Motorcraft EV-261

It's the only box I had lying around. The one you get shouldn't have the threading in it at all, it should just press in.
