Seems like to me we are talking pound of metal and magnets, against a pound of attachment hardware and screws.
Here are some pictures of how I am doing it. Note that I have hedged my bet with a hich pin on the top of the strut. I have ordered the more powerful magnets but I don't have them yet. I don't think the RS magnets will do it. The pictures show there are washers there to attract the magnets
