Castle nuts were used on the front end of the steady rods along with a cotter pin until they were replaced with slotted hex nuts (still with cotter pins) as a running change during the '33 model year. On the back of the rod, hex nuts and lock washers were used.

Is this cut out right? and not a hole. Maybe the screw head has worn away? will check.
I've seen more than few frames where the recessed stamped hole has cracked out of the frame, much as you describe the "U" shaped cutout.

Can a arc welded bead be used as a repair or should I weld a steel washer in place?

A countersunk washer would be required and it would leave the bolt higher than original, which depending on the thickness of the washer might be high enough to leave little or no threads for the hex nut after allowing for the thickness of a lock washer (on the bottom end of the special bolt).

Might see if someone has a damage frame that has that area salvageable.

Good idea, but how much of the car would have to be taken apart to gain access? My car has the stamped steel floor, how would that be removed? I imagine it would be easier to gain access if I had the wooden floor boards. Can you just remove the floor without disturbing everything else?

The part of the floor immediately adjacent to where the rod is attached is an integral part of the body and not removable separately. No North American '33 or '34 has a wood floor board in the area in question.

What Ted said. Wouldn't think it would be any more difficult than any other attempted fix in that area.

Reforming the counter sunk bit will be a exercise but as you say a doner chassis would help, A perch bolt nut has a pyramid shape to it could it be cut down and welded facing down to the chassis wouldn't be original but ,just something to think about ,

Finally got the castle nut off. I will try to remove the bolt. Is this end of the steady rod threaded for the bolt. or is it just a plain hole. It looks like a plain hole. The bolt was just stuck. Finally got is out The missing part of the cross member is attached to the screw head?
Soaking the thing in MMO. If the missing part of the cross member fits like a jig saw puzzle piece, Maybe I can just weld a bead along its borders?

Obviously that has been apart previously, as a plain hex nut and lock washer was used originally. Can't tell for sure from your photo, but the nut there looks to be a thread chaser and not the nut used on the bolt to hold it in place.

That is true. But what would have caused an entire section to be sheared off.
The piece fit perfectly into the section in my car. The piece is thick metal.
Maybe excessive engine vibration?
Anyway, I will put the piece in place and arc weld a nice bead along each joint. Chip and also grind down if needed. No need for any washers here. Will see how it holds up.
Thanks for your help

I would try and reinforce it by maybe welding it first to a square 3/16 section (stamping ),with a hole in it , doesn't matter if it sits lower than stock ,

Good idea. I'm surprised the original metal sheared off? My car seemed to run fine without this rod attached, because I remember seeing that strange hole when I was treating the metal floor and then painting it. Oh well, maybe the design was redundant and operates fine as long as there is at least one rod present.

Don't be too cavalier. The rods have a purpose. Should you not repair the broken side, if the other side gave way you might end up with the fan kissing the radiator, which is highly undesirable.

I will definitely will fix the right side. I knew the front of the engine is held by the two pads, but I often wondered what is holding the rear? I always just figured it was supported by the transmission?

You're correct...the rear is supported (up and down) by the transmission, but as David G suggests above, those rods are what keeps the torque tube from pushing the engine/trans assembly forward (into the radiator) on those mushy, stock rubber mounts. DD
