I talked to CURT today.
Trailer Hitches, Heavy Duty Hitch, & Towing Accessories Made in America by CURT Manufacturing.
If you have 370Z and live near Eau Claire, WI they would love for you to bring it by so they can fit it for a hitch. The 370Z is one of the vehicles on the "hit list" but they just don't have one to fit and start making them. Please please someone take them a Z. They said it would take about 3 days to fit it and get one right.
