My 07 Sierra Classic with a 5 speed trans has a bench seat and I'm looking to add a center console. I found brand that is called Rampage that will fit and not interfere with shifting. However, it is only held in by the center seat belt and the front of it will move side to side. Has anyone tried one of these and what do you think about it? Also does anyone have a source for plans and materials needed to fabricate a center console box. I did a through search of this forum and did not find what I need. Thanx in advance for the assistance!
