Default slug-tuned coils or substitutes?

I am trying to get some slug-tuned coils. I tried 4 different
electronics stores and searched online. So far I can't find them. I
found a few online, but not at the right uH value. I need them to make
a notch filter to block out a radio station (or summat) that is
interfering with channel 2 and 4 on my TV. The schematics and complete
info are on this page:

With inductors this size, you can hand wind the inductors around a pencil or
something of similar size and then spread or compress them after they have
been soldered into some kind of board. The inductors in MOST commercial
filters and tuners are made that way without coil forms.
