I modified mine and gained about an extra 2 inches. you will definatly need a welder. Plastic rivits and a rivet gun. No interferance with the gear shifter knob to dash or steering wheel to dash at all. Only wish I took my column completely apart so I could have greased the dry squeeky bearings

This was a tilt column BTW. I'm 6'6 and I can stretch my arm all the way out (sitting down durr) and my hand rests comfertably on the steering wheel.. looking back its one of those creature comfort things I should have done on my other silverado. Just didnt have the idea.
