Electrolytic capacitor replacement

I want to swap out a couple of electrolytic caps with higher quality caps, also electrolytic. The ones I am looking at are all physically bigger than the ones I am replacing, and consequently the leads don’t fit the board. The rubicon’s I want to bin are have a diameter of around 3/4’ and the caps I’m considering are between 1’ and 2’. The big issue I have is the lead spacing.

I’m considering using a spacer between the pc board and the cap giving enough room for the leads to bend enough to fit the board. I have space on the board to fit a larger cap, but not enough to mount the caps on their side. The caps new will need to sit “upright”.

Id appreciate it if somebody has figured an eloquent solution for this.

Thanks
