You want some more aggravation?
This is a INSTRUCTION SHEET from a 1956 BOOSTER INSTALL KIT. VIEW 9 shows going from a two port fitting for a three port (booster - wipers - dual adv dist canister) Much varies on how the engine was assembled OEM and what accessories the car came through with.
Parts Catalog Illustrations are not exact copies of ENGINEERING DRAWINGS. They are a culmination of similar years/assemblies. They show just enough so that the PARTS DUDE can find his/her/it/mutant's way in the TEXT.
