The wires posted from Mac's are close but not totally correct. The wires are date coded and the ones they sell are generic.
There are better sets available, if you correct boots and date codes try Marti Auto Works
Marti Auto Works - SPW-17 - SPARK PLUG WIRE SET - Steel Core.
Mac's wires are sold by most Mustang vendors and come from Alloy Metal Products who used to produce parts for my business.
