Well guys I can tell you that I'm a bit excited to purchase a system since I've never had anything thing like this in a vehicle of mine. If they have a 3/8" system Kevin and the speed thing is really not a major issue to me I'll have to take a look at it more (web site). Oh it was "C" Channel was it Dave? Oh by the round sides it looks like it was tubing instead. It's just that the brackets will be an easy fab and this will save a bit of cash for something else for the truck. Remember us old guys have a higher power to answer to; The Wife!!! This will also give me a custom fit for my truck too. Thanks again for the feedback guys I'm pretty confident on what I need to do.
