All of the aftermarket brake line companies separate the 67-69 and 70 year models, what is the difference from the 69 to 70 models on the 1/2 ton pickups... I only ask because I am getting ready to replace all of my lines, I am pretty sure the frame under my pickup is not the same frame the truck had originally. So, I need to Identify what I have before I order new lines.
