Plans or Pics for Front Wheel Dolly?

I put these under the frame rails, then secured them with a ratcheting tow strap around the cowl. I took all the front end off. The tow strap was only to move it over the lip in the garage. I could lift it up and the strap picked the jack stands up. These were made from snow mobile dollies. This was not very safe, and do it at your own risk. I saw where someone else made a stand with caster wheels to do the same thing. The stand stretched all the way across the frame rails. My roller jack stands were a quick fix to finish the front end. I do like to use them now, as I can roll the car when it is on jack stand, very carefully.
