A quick search of reproductions from a few popular sites include these images. It looks like several use the AMK image in their online catalogs. I've only included one image of those examples.
Pictures of my repro AMK purchased about a year ago. Notice the crappy alignment of the contact points
Also, if compared to the images of the OE example in John's PDF, you will notice several other differences such as the head of the screws (smaller), relays, underside components and so on.
The cover looks good.
The base looks good at a glance.
I have to wonder how well it will last. Originals didnt last very well, perhaps why Ford switched over later service part replacements to the electronic/solid-state versions.
It is easy to understand the OP's desire to use an OE FoMoCo version as opposed to any of the repros available because we already know the repros are failing faster than you can change them. Like the starter solenoids...it would be nice to have somebody build a reliable, correct-appearing reproduction. I intend to occasionally drive my restored 67 more than on and off of a trailer, requiring a battery charger on stand-by to have it pass muster at a show.
If anyone in the Parts Business might be reading this...perhaps consider building an example that looks as good as this amk product does that perhaps has the solid-state internals of the later service Replacements that Ford was selling.
