Has anyone ever seen factory high clearance brackets. I looked under my freinds 77 f150 high boy. They are like tucked up into the cross member and look like they would be nice with my arm extensions. I know these are factory because the guy bought the truck new and only put a 2" suspension lift on it with 35x14.50's on it. The thing sits as high as my bronco. If anyone knew where to get these that would be great.
