It has been a few years but all of those components were purchased on Ebay by me.
Jon may be able to supply all the components for the EPB. He can at least tell you which Tesla to get the brake caliper from. At the moment I don't remember those details. He can supply the adapter as well.
The Ford components are easy to get from one of the Ebay brake component suppliers. There are more then a few. The generic parts work fine.
You aren't seeing this type of kit available from any of the vendors simply because there is no motivation profit wise on their part. That is not what they are in business to do.
Actually most of the Ebay vendors that I have dealt with are better then any of my local suppliers which now would be through the NAPA system. Those people are just a bunch of numbnut teenagers who are lucky they aren't homeless and living on the street.
Most of the parts that I used they don't keep "in the store" and they need to source them anyway.
As stated, the rear calipers are just 65-7 Mustang. The front will be listed as 69 Ford Galaxie/Thunderbird.
You are on your own as far as the adapters though but things like that are not an issue for me to fabricate. They are pretty straight forward. Basically fabricated from simple plate steel.
The DT decal is just something that I printed out of my P-touch label maker.
