bov flange

I bought a TMIC from TJdouble07. He had a flange welded on the back of the intercooler, if I remember correctly, he got it done for $70.

Now I just need to save the money to get the Type-S BOV.

Ok I bought the t hose and I the hks bov arrived today but what else do I need. Do I need to get the flange also. because the parts dont seem to go along and seems to be missing something. The flange itself cant be bought 935 so where can I get it?
