If you are planning to jack the car up to put on dollies then I would just get crank up dollies such as Go-Jacks. If wanting to get it up on jack stands, you can pretty easily get a jack under the frame rails of a car already sitting up on dollies. I have a practice of always using two floor jacks to raise any of my cars rather than a single jack as I don’t like to stress and twist the frame. I either jack on both sides to get the front or back up on jack stands, or I jack the front and rear on the same side toget one side up for tire work or something.
For my 4-post lift, I have a set of wooden ramps about 5-1/2’ long built with 2x6 ribs and plywood decking so the radiator scoop, etc clears. I actually built them to do
oil changes on a 17 Shelby GT350 I used to own but I found they flushed up perfect to the ramps on my lift.
