Pics of dolly setup with no K member

I know someone sold a set of these however if I can just fabricate something on the bench I am all the better for it. Getting ready to get my car up on the lift for reassembly and I had a spare K member that I modified with HF Casters and sold it after I put in the current spot at the back of the shop.... So it's gonna need a little help on the front end to get this thing back together....

Pics of who has done this would be great....

TIA,
JW
