The engine/gearbox has to be pulled from the top as the chassis doesn't allow for it to be dropped out the bottom. Depending on the car...somtimes we'll strap it to the lift arms to ensure it's secure when removing large components.is it alot easier to pull out the top than bottom? seems like most work i see is out the top. Also do you have to add weight ballast to the car to keep it stable when removing the motor/trans. car looks great for the age, doesnt look like any real dirty work, everything is so clean.
