No those are reserved for the larger chassis set. It may have had a rubber washer between the chassis and baseboard but I would check the shaft alignment @ the front of the cabinet to see if they are centered. Most of the time there will be a recess cut in the baseboard for it. It probably had nothing.
>The tuner module is loose and I haven't really addressed the cause of that yet
There are 3 hex screws that hold it in place. These have special rubber grommet that hold the tuning cap in position. These rot over time and make the cap loose. RR probably has replacements I just make my own using rubber grommets from the store. Obtw it's not set up like that to isolate the the tuning from ground (for the avc circuit) but to prevent microphonics
The dial looks pretty good if the crack doesn't show in view I would just add a little bit of cynoacrylate to the back side of the dial. But I'm cheap. Oh never clean a phenolic Philco dial w/water use odorless mineral spirits water will erase the print in a hurry.
