It would be better if the other antenna was anything but 432.

I know that when stacking antennas for different bands on the same mast, the general rule of thumb is to space them at least 1/2 of the boom length for the higher frequency antenna. Does this rule also hold true for stacking 2 antennas on a horizontal crossboom? If I want to put a 2m and 70cm yagi on the same crossboom, how far apart should they be spaced?
