I don't know what the original crossover point was for those horns. I'm guessing it's in the neighborhood of 1,000hz. Here's a nice looking 1,600hz crossover:

18db/octave, so it's sufficiently steep that you shouldn't have to worry about any bass frequencies getting through.

Here's another:

800hz, 12db/octave. Not as steep, but still better than the original single capacitor (which, I believe, is only 6db/octave). But the more gradual rolloff may actually sound better, I'm not sure.

Of course, these are both designed for 8 ohm drivers. If the Kustom horns are 16ohms, that would change the crossover point, although I'm not sure in which direction or how much. (as you can see, I know *some* of this stuff, but I'm hardly an expert)

You may also want to add an L-pad (level control):
