So apparently you can no longer buy a factory Mitsubishi OEM MB629056 ECS replacement suspension controller. They are no longer available and have been discontinued
I found out when a mechanic from an automotive repair facility who was working on a 3000gt called me and ordered a Techworks ECS aftermarket replacement instead.
I called my local Mitsu parts department and they confirmed and Cherry hill is showing the same thing.
