I agree, the vendor anti-squeak is way too thin. Same for the transmission floor panel. But, the vendor gaskets make a good template to cut your own from heavier material. I am not at that point yet, but am either going with 30# roofing paper, or will use a heavy "gasket" material available at most FLAPS. Just not sure the gasket material rolls are large enough for every piece of anti-squeak needed.
