with axial capacitors you can just put a bead of adhesive under them and its away from solder joints and you can slice it off easily to remove
drilling holes in a 8.5 digit meter is not my style, its both insulting and provocative
plus, in that meter of meters, I think you want the shield of the cap to be as good as possible, and use axial.
you can still fix it with dp270, fiberglass shred and a axial capacitor
Like if I got that from you I would probobly patch the hole lol
you know with a axial cap, the case typically has spot welded lead on it, the negative side. I think there even exist some reverse polarity capacitors that have positive case, for negative rails, so you have the case tied to earth. its like bypassing shielding
