Does anyone know where I can find a decent set of wheel dollies, I'm looking for the one's that you can sit the jack stand on top of them.

anyone? Do you think it would work to get some heavy duty casters and some 2x4 and make some. They would mainly be used for moving the frame in and out of the garage.

I got a set off ebay for about $80 ( set of 4 ) and I had set the jackstands on them and put the fram on the stands. It works pretty well. I have wheels and tires on now but it will work and the price was right.

I bought a set from Northern Tool and Equip a few years back. They are made of steel and have rectangular flat pockets that hold jack stands very well. In my opinion they are lot nicer than some of the ones you see today that have a curved base.

Here's the ones that I bought. Not cheap but worth it.
