The other day, I got the manual steering into the one rolling frame, which allowed me to steer it into the garage and test fit the engine.
I did test how far I had to turn the wheel. The manual steering gives 6 full rotations, while the power steering gives four.
Also, I got to stop over to see Daox tonight, and got an electric radiator fan (from a Toyota Paseo?) and a 12V DC vacuum pump.
The electric radiator fan is more efficient than the mechanical propeller on the engine. That, and I somehow misplaced one of the parts that would hold it on anyways.... The vacuum pump will be used to run the power brakes when the vehicle is on but the engine isn't, similar to how I'm using an electric vacuum pump in the Electro-Metro.
Because the engine has a mechanical vacuum pump on it, which may or may not be running while in hybrid mode, I think the simplest thing to do for the power brakes is hook both vacuum pumps up to a tee going to the vacuum reservoir, and have one-way valves on both pumps.
