The bakelite block caps are replaced by taking the old caps out of the block and putting new modern caps inside the old block. There is a nice thread at this LINK that shows how you can do it without desoldering everything, although I often take them out completely so they are easier to clean up and stuff.
There is lots of information on which blocks have grounds and on which terminal at this LINK.
