I made the mount to use 2 of these magnets from amazon https://www.amazon.com/gp/product/B07L2S9KTX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 you will also need 2x 3/4" 10-32 flat head screws and 2x 10-32 nuts to bolt the magnets in place. There's also holes for #6 screws if you would rather attach it to something that way.
