Dual point Mallery dist. were part of the Formula S package in 1966. It may have also been used other years. Not use if the shown is the Mallery.

Just to clarify, the HP 273 dual points were cast iron housing units made by Prestolite. The correct numbers for 1966 were Model # IBB-4013a Part #2642242 and replacement
#IBS-4013AB and #2642461 for non CAP (Clean Air Package {California Emissions})
The CAP part numbers were #IBB-4013B #2642358 and replacement numbers #IBBS-4013BB and #2642405. tmm
