Ordered them from you. They were too small in diameter. I used a hot glue gun to anchor the feet. The fix is still working. I took a torch to the grate where the feet ride and didn't heat them to glowing but close. I then gooed Gorilla All Temperature Hot Glue into the ports and pushed the feet in holding them in place with a screwdriver until they DID NOT try to pop back out.
Part number on the Gorilla bag appears to be1659B
