I did the exact same thing a few months ago, installed a fresh steering damper. It was a little scary when you have to turn that steering wheel while on the Rhino Ramps, but it worked out, turned it just enough to get to that freaking nut. I considered turning it upside down, but then realized that bolt is located in that position so it doesn't fall out should the nut work its way out.

I am using the 16,000 lbs rated Rhino Ramps since I originally bought it for my RAM Rebel truck, but really happy with the durability, especially when having the turn the steering wheel with the front of the car on them.
