From my calculations, assuming his center frequency was 51 mHz, he used

odd to me, as it would translate to 467.5 feet which is number I've
never seen before.

468/f is the length of a dipole adjusted for end effects.

Anyone have any ideas? Will this work? How do I calculate the stub
length?

Why not use a Xc = -j150 cap? I get 0.176 wavelength for a
capacitive stub which may be inconvenient at HF.
