No problem, Dave. Just wait for your stones to come in, Put them all together and measure what dimensions you would need for the interior. Remember to account for the thickness of the foam that you want as well as anything else you might want to store in there.

I'd call Pelican and see if they have anything that doesn't have the "pick and pluck" foam, too, since it might come out over time. Or, just take out whatever foam is in the container and glue in your own foam.
