I don't think you can beat just buying a new stand at HF. I have a four wheeled one that seems to be plenty. My three wheeled on had my Rambler motor on it and I would roll it out of my garage and back in over and over and over (WAY too many times) without a problem, even over the hump of the garage floor at the door. But I do have to say once I wasn't paying attention and it came up on two wheels a little!
It scared the living crap out of me! Not only would that have busted a lot of stuff (possibly falling on my Gran Sport! I could likely have been busted up too!
Don't screw around with it, that I will tell you, take it seriously.
