Jack's Comments:

New reproduction yellow top coil with silver inked FoMoCo stamped and date coded to the date code you specify. We repaint the coil with the correct durable satin flat black catalyzed paint. To make it look even more like factory originals we overspray the lower edge of yellow top insulator.

MCA and SAAC are now deducting for the sticker version so this is a good option if your original coil is in poor condition. Accepted in all judged classes except in Survivor and Thoroughbred classes.

The terminal thread is unfortunately metric so we installed factory looking zinc captivated star locking nuts. I can't believe the manufacture made them this way but like many repro's today there is almost always an issue.

Specify your cars year, engine, generator, alternator so we can apply the stamp in a location that will be seen when installed.

*See picture below that shows how to read coil date codes 

Selecting a date code tips: 
We suggest selecting a date code that is not closer than two weeks before your cars production date. The general rule of thumb is to select a date 1-2 months before your cars actual production date.

Common Questions:
Q: Whats not the same as original production coils? 
A: The yellow color and finish is really close to originals but not exact. Doesn't have date/mold code in between terminal. Metal sleeve at the top of the coil is not as wide as originals although the width of originals vary.

Q: Are the new reproduction coils as bad as the old ones? My old repro coil crapped out on me after only one summer.
A: So far they seem to be very reliable. I wouldn't expect them to be as reliable as the originals. The manufacture says they perform extensive testing before shipping but time will only tell in the end. I will report any issues as our customers give us feedback.

Q: Whats the earliest Autolite stamped coil?
A: See picture below of a coil we found with an October 1966 date code. Exact change over date from the FoMoCo stamped coil is not know.

Q: Does the location of the coil differ depending if my 1965 Mustang has a generator, alternator or AC ?
A: Generator equipped cars had the coil mounted on the intake with the yellow top pointed towards the front of the car, terminals in the 4 and 6 o'clock position (clock positions on original cars varied).
A: Alternator equipped cars had the coil mounted on the front of the intake with the yellow top up and the terminals in the 12:30 and 2:30 position (clock positions on original cars varied).
A: AC equipped cars didn't have the coil in a special location.

Q: The coil stamp states "Use with external resistor". What does the external resistor do and where is it located?
A: Your external resistor is a special resistance wire located within your production wire harness. When the turn the key to start your car the coil is fed full battery voltage from the starter circuit for a stronger spark. Once the engine is running the voltage is routed thru the resistance wire to reduce it to around ~ 9 volts. It's always a good idea to check if you have these voltage readings at the coil at startup and while it's running.

See last three pictures that are from the Ford Shop Manuals on how to test the coil and resistance wire.

Warning: This repro coil and original coils will overheat and fail if they are run at a higher voltage for an extended period of time. Engine feed resistance wire out of spec (see Ford Manual for testing below) or leaving the ignition on for a prolonged time are the two most common issues.
