Guys:
For those wanting a nice look, a good price, and a simple install, I recommend this one from Autotrimming (available on ebay):

It's made specifically for the 370z. It's available with several different stitch colors, and it's only about 23 bucks. Best of all, it's easy to install. All I did was carefully pry off the rectangular rubber seal around the base of the e-brake. Then I slid on the gaiter (a cinch!) and stuffed the bottom skirt down through the opening. Then I reinstalled the rubber seal. It's held in with about 15-20 little rubber tabs that stick through slots in the plastic center console.
Here's a picture of the finished product.
Cheers,
Steve
