31 Model A rear spring

[tommyleea]

I have a question concerning the rear spring on a Model A, vs the rear springs on a normal/newer rear leaf spring car. On the regular leaf spring car, if you take the weight off the rear axle, you can disconnect the rear springs from the body/shackles, and remove the axle and springs without issue. Why is it so dangerous to do that with the Model A. If you take the weight off the rear axle, why can't you disconnect the spring from the body, and remove the axle with the spring attached. I have read articles on the subject, but still confused. Thanks..TommyJ..
