Michael, Why would you want to go 75 mph in that truck. At that speed no one will have an opportunity to admire it, plus you'll reach the other side of the island before you get it stopped.
You're certainly going to need a bigger carbie to be able to reach that velocity.
Up here we don't call them carbies but I knew what you meant.
Good luck with your project and the above comments were for laughs with just a little truth along with.
Dan
