There must be several HEI modules that'll work. Anyone care to explain a "low saturation" module? See ad below:

Probably marketing gobbledygook but may refer to controlling the dwell so the coil doesn’t oversaturate, which I think all HEI modules do anyway.
One of the nice features of the Ford coil is that most of the aftermarket e-core coils that come in those finned aluminum housings use the same hole pattern so it’s an easy swap if you want to upgrade the coil later.
