I borrowed oer from a member here and the Post Office lost it on it's way back to him, I sent it the same way it was sent to me (even the same box).
Make sure you wrap it good and no loose parts inside to get out if the box is damaged.
Because of the insurance, it did not cost me much to replace it.
I will say this. Using the tool it only took a minuet to do both so it is well worth having the tool to do this.
I used a large two jaw puller and a big ass socket to remove and the same puller with a large thick flat washer to install. Not doubting the tool helps but it's not absolutely necessary esp if the car isn't a rot box
