What is a "variable reluctor pickup"? Does this pickup off the distributor
cam using some type of disk and magnet? Currently, I have single points
and I want something to replace them that does not wear.

[the variable reluctor pickup is standard on all 260 and up stock distributors.
There is a star-like mechanism that rotates and a coil where the points
used to be. When the star aligns with the coil pole piece, the reluctance
of the magnetic path is radically changed and that induces a pulse in the coil.
The later model distributors are slightly larger than the points ones, a
desirable property. They are cheap from salvage yards so that is the
recommended course of action rather than trying to backfit a pickup to
a points distributor. JGD]
