In many US states, there are no vehicle inspections, so as long as it has the basics like turn signals, wipers, brake lights, headlights, etc. it can be driven on the street and nobody will care.

Yea, I did not realize the huge difference moving from the east coast living in a few cities there going through the detailed inspection. I moved to the south, a different city, brought in my car, they told me to turn on my signals and hazards, asked for some money, and gave me a sticker. Very different.

I don't think there should be any regulatory problems. I'm in Oregon. I think I just have to tell them it doesn't have an engine anymore to be exempt from DEQ testing.
