The alignment shop won't even know it's different unless they check the angle of the right wheel when the left wheel is turned away from straight ahead. The shorter idler arm will make the Ackerman angle be wrong in a turn, but the car will still track fine straight ahead. I can't estimate the danger, but driving a car this way will have more of a tendency to understeer, and to go into a skid on slippery surfaces, because the two front wheels will have to slide slightly in a turn. Maybe this is too small an effect to notice, but they must have made the Imperial arm longer for a reason.
