Wanted to ask if anyone knows about or has a complete list of parts from other Ford products that are interchangeable with S-type? Trim pieces, mechanical stuff, etc

 

It certainly would be handy. I could use one too. all I can tell you is that you can use generic relays in place of the Jaguar part number relays. just make sure the coil resistance is close to the same and it’s not easy to find what those resistances are supposed to be. the data on the relay characteristics are not readily available. so I just based my relay search on the coil resistance that I measured on my own relays that I had in the car already and tried to get something close.

 

Here is an old thread with crossover parts:
