pending on how long you want to wait, contact nissan north america. I got mine from them due to the fact that my car was running 240s from the get go. I got the 34 row cooler kit installed and a oil change at $0 cost. I think they want me to keep purchasing nissans lol. But I purchased my thermo adapter plate from gtm and ordered my an10 fittings from mocal so i can keep my an-10 lines. GTM wanted to charge me almost 900 for hoses and fittings and labor and plus it would be a smaller line. No thanx.
