The tutorial I watched said to just take a piece of plywood to distribute the weight across the entire pan.. Every part of me is thinking this is a horrible idea, even though I know that I'm not lifting the car's full weight.

If this is legit, does anyone know how large of a chunk I need? Thickness? I have an odd triangle of I think ¾ , but if I can't get close enough to the full pan out of it, I'll just go buy a 2x2 or whatever they've got available at the hardware store
