I'm in the process of putting together a 1JZGTE with a CD009 trans. I had the bellhousing milled .5" a long time ago when I was using the same trans on a SR20. I happen to have a ATS Carbon twin plate clutch for a 2JZGTE. Now looking at the parts catalog for ATS, all of the discs and pressure plates for every kit offered for a Japanese car are the same. The unique part numbers are only for center hubs (where the input shaft goes), and the flywheels. My hope is someone with a 350/370z version (can be literally any ATS multiplate clutch, they share hub part numbers across the board) would take the time to measure the length of the center of their hub for me so I can see how tall it is compared to my 2JZGTE one which is 2" tall. Image below for reference



This is the spacing I'm working with.
