Welcome to the Phorum!

Maybe my forthcoming comments aren't needed; but, it looks like there are 3 capacitors in the can.  #21 is an 8 mfd, #21A is a 16 mfd, and #21B is a 12 mfd.  There should be markings on the side of the can that identify the internal caps.
My preference has been to add the new caps under the chassis (I'm more a refurbisher than a restorer).  I sometimes will add a terminal strip and mount the new capacitors to it (see photo).

Also, the #81 bakelite block has quite a few wires attached to its terminals.  I've read Mike's procedure on how to do it without desoldering the wires and removing the block; but, the ones I've done like #81, I've had to desolder the wires and remove it for heating and digging out the two .01 caps that are inside.  I guess I'm just not skilled enough to do it without removing the block.  There is a part number on one side of the block.  Could be something like 3903-DG.  Use the part number and go to http://philcoradio.com/phorum/attachment.php?aid=10650 to see details of how the caps are wired in the block.

Good luck!
