67 Deluxe Door Courtesy Lamp Harness

if you're talking about the door/pillar wire pass through grommets and even better version is to rob some off a jeep cherokee (XJ 80's or 90's) the holes are the same size and they are actually identical to what ford used on the 71-73 stangs with the bellows type rubber tubing style. if you want the stock style grommets probably any 60's or early 70's ford will have the same type. the advantage of the bellows type pass through is you can larger speaker cables and you'll have more room for other wiring like power windows and locks or whatever as well.
