Hipbelt webbing source

I recently sewed a backpack and while I struggled at times sourcing the materials I eventually found what I needed -- with one exception. For the hip belt I want to use 2" flat nylon webbing of an appropriate grade, the same grade as on my old backpack.
I already have two lengths of different 2 inch webbings but they are too thick and heavy for the application:
63 g/m - 2 inch "seat belt" webbing
70 g/m - 2 inch "flat nylon" webbing (thickness 0.070-0.075 inches) from strapworks.com
I have several other backpacks, day packs, etc, so I have a pretty good idea of the type of webbing I want. I suspect it is something between 1/2 and 2/3 the weight/thickness of the webbings that I have. I've even found a supplier, but they only sell by the roll.
Does anyone know where to obtain 2 inch webbing of a "typical" weight for backpacks?
I live in the U.S. but at this point I might be willing to ship it from Mars if I could source it.
