^Roger that, I did almost the same thing on my Koyo. Instead of gluing the foam strip to the Koyo with epoxy, I used a only the hook side of an industrial-grade adhesive backed velcro strip that I stuck to the bottom of the Koyo. The foam strip attaches to the velcro very securely, but you can remove it when needed for servicing. Figured that to work on the oil cooler lines, or draining coolant, it would be nice to be able to get the foam strip out of the way so it doesn't soak up any fluids.
