I am getting ready to take the suspension out from under my 69 RR
and I am looking for ideas on how to move it around in my stone driveway easily. I got some wheels from harbor freight and they are not heavy duty enough, 300 lbs cap each, and they are half flat with max air pressure with the car weight on them. I don't think small wheels would work well enough in the stones.
I have brackets made for both ends of the car that bolt to the bumper bracket locations. They have a 4" square flat steel plate welded to u channel steel and flat plates where the bumper bolts go thru. Not looking to spend 500. to buy the US car tool ones.

Any home made ideas for some or wheels that will hold the cars weight that I can attach to my already made brackets ???
Any Ideas or Help is Appreciated.
