Aftermarket Fuse/Relay Board Mounting

I have all my "extra" fuses , relays and MSD unit mounted into what would have been my glove box. 68 Barracuda. Im in the process of a wiring tidy and renovation, was under the dash on the weekend and wondering where I could mount all that gear so I can have my glove box back and have some more room to get at it if need be...I thought maybe make a swing down panel and when not needed swing back up under dash and be somehow secured under there....How have you other guys mounted yours? Doesnt look like a lot of inner firewall real estate under there
