I basicly use my trucks daily, running errands, & feel safer running at the speeds the designers of these trucks meant for them to travel. If I need to get somewhere in a hurry, I'll drive something else. If someone else doesn't like the speed I'm traveling, they can pass me. I always seem to get "Thumbs up", & not "The Bird". Just seems to destroy the character, of a old truck to modify it too much. I'm a "purist", & not ashamed of it. Just my outlook, on the subject. I just see so many Vintage Trucks, & Cars, that are subjects to mods, for the purpose of traveling faster. Then wind up failed projects, that are too far to the other side too rescue. Then end up as parts vehicles, or in the scrap yard.
