You'll only need one adaptor from ICT billet if you have the quick disconnects on the radiator. This is available from summit racing, etc.
The only custom piece you'll "need" from
@mrblaine is the stainless tube for the passenger side of the setrab.
He supplied me with the AN fittings, but ended up needing one 45 hose barb fitting to connect to the stainless tube. These AN fittings are all easily available from racetronix etc. But probably easiest to get them from blaine. You'll also need -6 hose. I got aeroquip from summit, but I think Blaine can supply that as well.
My experience is pushing the hoses onto the barbed fittings is pretty tough, but I'm also an idiot. I think you can buy a fancy tool to do this.
