Update:
I had been considering leaving the 3.0 completely stock and selling ya'll the SVT parts, but I can't get over not having the engine bay look as it did when purchased (meaning the SVT badging on the UIM)- mainly in the event I have to sell the car.
Anyway, just got back from the machine shop to discuss with the TIG guy what I was thinking of doing. Also having a printout of the adapter plates to show him ... well, his opinion? Use the plates.
