I just wimp out on a situation like that and connect to the old cap's leads with J hook style. Maybe use a mandrill, using a small nail just slightly wider than the old cap lead, wrap the new cap's lead around it in a spiral pattern and then bend the lead 90 degrees to make it a straight butt connection with the old lead on the circuit board. This avoids having to attempt to remove the circuit board, and damage or mistakes with associated wires with the board. Do it neatly and it won't be that ugly.

Above j hook method isn't usable for that, unfortunately.
As you'd probably have less than 2 mm of lead to work with, trying to solder to that without unsoldering the lead from the board backside would be dicey...
