^ I think that's going to resolve the issue of "bottom box". That Craftsman stack was flimsy as hell - got rid of it about two weeks ago. Sold the smashed CM top box a couple days ago. Working on a CM "Crowntop" right now that I might keep. Yours is still out in the garage.
Thanks @Crabman ! He graduating with a masters in architecture. Has his BS in Arch as well as minors in construction management and interior design. He is happy to be done!
