oem motorcraft spark wire set

[ELGT4me]

Hi guys, first time poster & confirmed landlubber from Australia. I am trying to locate the correct spark wire set for my GT 40 engined car. None of the Mustang guys can help me & the part is obsolete here in Australia. The base engine after much researching, is actually a Marine version of the Windsor 5.0 liter engine. The correct spark wire set is grey in color, the distributor ends suit the HEI type distributor, all the leads are numbered to their allocated cylinder & have "Motorcraft 1995" printed on them. The spark plug ends are angled (115 degrees?) & have orange spark plug boots on them. My engine is "tubular GT 40" upper & lower intake, iron gt 40 heads & 24 lb injectors. It also runs the Cobra 1.7:1 roller rockers & hydraulic roller camshaft. I have 2 Ford Australia pt no's but I think they would not mean a thing to you guys. If someone can help with the correct US pt no, or know where a OEM Motorcraft set is located, I would be very grateful. In case your wondering, I need the OEM wire set for a concourse restoration on my car.. Thanks in advance, Greg.
