With Halloween coming up I want to have my car in the local parade, but I don't want to go through the entire process of changing the car. I think a cardboard mock-up on the back will suffice for a local parade.
What I'm asking for is some dimensions on some of the parts of the rear reactor. The exhaust fins and the plutonium chamber. I can look up the rest, and I work in electronics so I have spare parts everywhere.
