Exactly right John, the bracing should go on before the car is lifted front or rear, 1/4 inch now in the door gaps when somebody leans on it, can you imagine if it's not braced and over time, turning it around a few times to work on the bottom??? Get the car level with even weight distribution, if at all possible with the doors on and brace it.
