TC,
We try not to leave much to chance. We made the pads ourselves and riveted carpet to them to not scratch the frames. The flat pads gave me the "Willy's" and I couldn't deal with it. I was working a car once and someone on the other side pushed or pulled, or something, and the car slid. The cars are so light I just couldn't stand it any more and so I made the pads.
I would recommend them. Better safe than flat.
I guess I worry a lot.
David
