Jack's Comments:

Our concours correct 1969 Autolite alternators are built with 100% new components manufactured to our specifications to be reliable and look factory original.  We faithfully reproduced the unique front and rear housings from original Ford engineering drawings, 19 lamination yellow/amber varnished 42 amp stator and we even apply date codes that correspond with your cars production date.  Our alternators also come with all the concours correct hardware you need to install your wire harness and fan/pulley.

Concours Notes:
1) Alternators produced from the start of 1969 production until the end of February 1969 production had the AUTOLITE teardrop style rear housing and two Autolite ink stamps on the rear housing. If your car has a production date before March 1969 this is the correct alternator for your car.
2) All alternators built before March 1969 had two Autolite ink stamps on the rear housing. Around the end of February 1969 Autolite decided to move from the ink stamp ID to a die stamped ID on the front housing. Depending on each assembly plant inventory turn you could see either a ink stamped or die stamped alternator.  What we are trying to say is there isn't an exact date the change over occurred so you will need to decide what is right for your car.
3) The orange Autolite ink stamp color identifies this as a 42 amp alternator.
4) The correct cooling fan has 13 blades and it had a yellow zinc plating (also known as zinc dichromate).
5) The correct pulley for this alternator is a single sheave pulley with a yellow zinc plating (also known as zinc dichromate).
6) The wire harness terminal and nut/pulley hardware had a yellow zinc finish in 1969 (concours correct hardware included).
7) Just like the factory alternators we apply a tiny dob of light brown sealer seen on the rear housing between the rear bearing hub and the FLD terminal. This was used to seal a small hole that allowed a pin to be inserted to hold the brushes in place during assembly.

* BOSS 302 Notes
1969 Boss 302 production started April 14, 1969 thru the end of the year. It is possible a very early 1969 BOSS 302 came from the factory with an ink stamped C6AF-10300-A alternator.
Very early production: C6AF-10300-A ink stamped w/C5AF-10A352-L Pulley
Most of production: C6AF-10300-A die stamped w/C5AF-10A352-L Pulley
Very late production: C9ZF-10300-E die stamped w/3.87" C5AF-10352-H pulley
No cut-over date to C9ZF-10300-E known

Questions & Answers:

Q What do yo mean actual output is 55 Amps?
A: 
The Autolite ink stamps on this alternator will show the factory 42 amp output but we build all our alternators to produce up to 55 amps so it can support some of the modern accessories available today.  The alternator will produce as much amperage as your cars electrical system demands.  Having this slightly larger max amp output will not damage your electrical system and will help the alternator last longer.

Q:
 
How do you decide what date codes are right for my car?
A: 
When you specify your cars production date we take a look at our vintage calendars and select a day one to one and a half months before your car was built.  If you would like to specify a date you want your alternator stamped with just let us know in the Special Instructions: box.  Note: The stator was manufactured before the alternator itself so the stator inspection date is typically 7-20 days prior to the alternators two final inspection dates. 

Q:
I don't have a door tag on my car, what should I do?
A: If you don't have a door tag to get your cars build date you can calculate an approximate production date by locating date codes on your engine, rear axle or sheet metal parts.  You can then enter the dates you found in the Special Instructions: box before adding your alternator to your shopping cart.  We will use the date(s) you provide us to calculate a appropriate production date for your alternator. If you don't have any build date information or just don't care please choose that you want a generic date code.

Q: Where are the date codes located on the alternator?
A: Month, day and shift on stator. Shift, month, day, last digit of year on the side of the rear housing.

Q I'm running a NOS mechanical voltage regulator. Will this alternator make my regulator malfunction like the last alternator I purchased at my local Auto parts store?
A: You won't need to buy another voltage regulator. We build our alternators with components that are compatible with vintage mechanical or the new solid state voltage regulators just for this reason.  Note: Voltage regulators are the most common reason your battery is not charging or over charging.  We suggest you install a new solid state voltage regulator with your new alternator just to be safe.
