All we have available to us now days is 30# asphalt felt
paper, you know, roofing paper. That's exactly what the
vendors are selling also.
When I first got into my truck a decade ago, I'd ordered
one of the pre-cut kits and the piece I got had the white
lettering or chalk lines still on it indicating it was
just that, roofing paper. In my case it was not even 30#
material, it was 15# so....I cut my own from a roll of
30#. The original anti-squeak was the same type of material,
i.e., felt paper, but it was a heavier stock than even the
30# material. I believe it would have been more like 50#.
I've been looking for years for material heavier then 30#
but found none so far.
