You just need to drill a 20 mm hole in the center of say a 1590B hammond box. Make sure the display is in the center of the hole and that you can see the active display completely. May need to move it some. Then use some RTV silicone to hold it in place. I use Insta-cure gap filling 1oz Bob Smith to glue the cradel in place make sure the glue is no going to get on the display. I would not put glue on the part that goes in the hole as it may creep out onto the finish. IF used in a Hammon 1590B box with two batteries you can get away with RTV or Hot gluing the board in the mount. The batteries will hole it in place in the mod.
