I can't tell which item you are referring to as having a missing knob. The antenna valve and speedo reset are stock items but the next item over with the glare and the next item with black bracket and maybe a red light?? are not stock nor do I believe, Packard items.
Here is a photo of the reverse light switch bracket but I don't have precise dimensions. It is made of fairly thick metal -- probably around 2.5mm -- and needs to position the switch plunger over the bottom shift lever to that when car is in reverse the plunger is pushed into the switch. The bracket width is the same as the gearshaft mounting bracket and as you can see, bent up at 90 degrees. The bend on top is about 1 inch or 2.5cm on one side and the other end is longer at about 1 1/2 inches or 3.8cm so when it is bent in the opposite 90 it places the switch at an angle so the lever can move full travel yet still have the switch perpendicular. The hole is 1 1/2 inches or 3.8cm from the top bend and about 1/2 inch or 1.3cm up from the long end of the bracket. Except for the mounting bolt spacing, none of the dimensions are terribly critical as long as the lever is able to operate the plunger.
On the antenna, I seriously doubt you will find a new mast assy. Many have been looking for them as well as looking for complete vacuum antennas themselves. If you do find one be prepared for sticker shock.
If you have a complete antenna now, the best bet is to repair what you have. My antenna was inopertive and aside from the vacuum portion which was not functional, the sections were stuck too and did not telescope. I was able to use penetrating fluid, gentle persuasion, a little heat and mostly patience to free the two telescoping tubes. The vacuum portion was rebuilt.
Here are a couple of photos of the 47 version of the antenna. Yours is almost identical except the neck thru the fender and top nut are smaller. I believe the basic vacuum portion is of the same construction but maybe has a different diameter along with the smaller neck. The largest moving section has a piston with two leather cups at the bottom. My originals were rotten and seriously damaged but I could not find new modern leather or even rubber cups in the proper size. If you have access to metric brake parts maybe a pair of those rubber cups could substitute but US sizes were not close enough. While a cup shape would be better, I wound up turning a piece of Delrin on the lathe to make a support for wrapping a leather cord around it to make a new piston to size.
There is also a rubber seal at the top. That is two formed rubber discs and as far as I can tell are special items and also not available. I retrofitted a modern neoprene seal but had to do a bit of custom work to make it fit. Not knowing if yours is the same because of the narrower neck, I don't know if the seal I used will work.
