I'm about to embark on the replacement of a faulty pink resistor wire. I have the motorcraft replacement and shop manual that lists the details, but until I'm under the dash it's a bit unclear. Does anyone experienced with this have any pointers or wisdom that will help with this?
Thanks

Greetings all,
Hoping someone can chime in to assist.
My 1969 GT500/C6 stumbles under load only when engine is hot. Runs fine at temp in park/neutral but dies in drive when hot. The only mod is a pertronix 2.  All gauges function, including tach.
I changed out multiple yellow top coils and now have tried a Flamethrower coil. I am pretty ignorant with solving electrical issues, but can post what I know.
The coil is getting 12v at start but goes down to 10.6 on run. I realize that the resistor wire may be an issue (I have read the voltage should be 6-8v on run) with too much for the yellow top but not for the flamethrower (prefers 12v). When the ignition switch is bypassed (coil to battery) the stumble issue is resolved. The stumble is also resolved with a direct bypass from ignition C terminal to coil. The issue is not resolved with bypasses of the first 2 connectors off coil (? part numbers 14289 and 14L290 as listed in the 1969 Shelby Shop supplement).
Can the tach be the source of my issue even if it's functioning? Why would the issue be temperature sensitive? Any comments appreciated!!!
Thanks

I'm looking to get the rear license plate bracket on my 1969 GT500 redone in its original finish which appears to be a "hot dipped" galvanization. It seems most shops will only do large runs and charge $250-500.  Does anyone know of a shop that will do small part runs? Or does someone have an NOS/great used bracket gathering dust for sale? Thanks
