I wouldnt go more than 65mm....
keep it mind, its plastic.

I spend 10$ on the 2 adapter that I machined at work and a couple hours.

The 370z as you know has 2 TB and they arent interchangeable.
the plug arent pinned the same from both side.

Like I said if I remember correctly its the driver side that need to be re-pinned like the passenger side.

that was my secret mod at the time just before I blew the VVEL and then well it was put on hold. Never tried the setup.
