When I bought my Supra in 2005, I tried to order a New Dimension tower. I waited 3 months, and kept getting the run-around on it. I finally canceled the order and told them to eff-off. I then ordered a Titan tower and had it inside of a week. I should have went Titan in the first place anyways, they're a much stiffer tower!!
Titan has now been sold to Malibu, but I believe a new company is starting to make the old Titan towers again. They're called Star One Wake. I would track them down.
