I show off the TMA feature often - 2 chassis with tuner standing on end now in my shop. I learned about it from my first employer who refused to work on any SS consoles in the late 70s. . IIRC There was a similar provision made for XL-100 and even later "jiggable" RCA chassis.
Im pretty sure Zenith has a pair of screws like that on the 66 and later models,
But yeah - like Zenith needed it. RCA had to do something if they weren't planning on putting in a $ervice $aver access panel on bottom of the cabinet
