I did send an email to the company and a message on their FB page. Both said the stand would fit. FB person said that it would have to be angled in so I assume there a brace, but not in the center. Still no pictures of the back even though I asked...
Custom means getting my husband to make and he could. He'd make it strong enough to hold a house. He once made me an aviary that rivaled the tiny houses of today and an awesome sewing cabinet as big as an execs desk, but he's working 6 days a week and would rather work with his mill and metal or plastics than wood. I'm also not sure it would be any cheaper. The R&J cabinet is 404.00. Guess I'll get it and if it doesn't work, I'll return it.
