It appears that you have TRS normal-through jacks that fasten to the  
rear of the jack panel with a single screw.  (Switchcraft will supply  
those screws if  you don't have them.)

I'd expect no trouble soldering to them.  You may need a tiny bit of  
flux, or possibly some wire brushing if there's an y corrosion on the  
tabs.

These appear to be the sort used for the Looping jacks in the small   
63 C 1  switchboard I sent pictures of.  Except they are TRS not TS  
types.

I would look for some of the more complicated "SET" type jacks (I  
don't have the switchcraft nomenclature) - the WE number is 438C from  
the diagram.  A small number of those may make your life nicer - and  
establish the set of functions that the 63C1 switchboard has.

Do you have a 19 inch rack jack strip with phenolic for the material?   
That would me most useful.
