Capacitor on my pool pump gave up the ghost; it fits very snugly into an external housing atop the pump and I can't seem to find a replacement that fits.

All of the 50uf/370VAC models I found (like this) are taller and slightly wider and don't fit.

I was able to find a 25uf model that fits and installed it, and pump is currently working.

So I have 2 questions:

1. are there are 50uf/370 capacitors out there the same size as my old one?
2. any problem sticking with the 25uf one I currently have installed? Will it cause my pump motor to overwork? Or maybe just the capacitor itself will have a shorter life (if so, that's ok; they're cheap and I can just buy a couple to have on hand)?

Thanks for any help!

EDIT

Thanks to u/Dartmouththedude who pointed me in the right direction I believe I have found one that will fit:

First, let me say that with the help of some of the folks here I think I have found one that should fit. So no need for further replies - thanks!

But to try and get ahead of the many "size doesn't matter, get one and strap it to the side with some sheet metal screws" replies, I'll add here that there is no box or large HVAC unit here with room inside, the capacitor must fit into a metal housing that is just barely larger than the old (busted) capacitor.

Pump looks roughly like this; the capacitor had to fit inside the metal half-dome cover on top of the right side of pump. So if it's going to fit it needs to be the same size or smaller.
