Yeah, I figured.
I called a local Nissan parts dealership asking about the trim and they said they couldn't sell the trim alone. The whole pedal assembly needs to be sold together.
I was quoted ~$390 for each pedal (clutch, brake, gas) = ~$1,560. I'm not gonna spend that much money for aluminum trim; not to mention installing the pedal assembly.
I guess the 350Z is a lot easier to install as opposed to the 370z which is probably why Nissan hasn't released a pedal trim kit yet as an accessory.
Hopefully Ultimate Pedals can make one that looks and fits like the 370z touring model editions. I guess we'll just have to wait and see
