It'll be hidden inside so luckily I can get away with the plastic exterior.

The original cap is the big silver one on the upper left. I can't get anything bigger than a 25 or 30 uf in there now .

30uF will help. You can also look at Solen caps, which are pretty compact (though pricey).

Have you a link to an example at all please? I'm quite good at getting the wrong ones...

Could I use a few smaller ones linked together to create a larger value?

Yes, you can connect them in parallel. I believe 47uF (PPE4700) is the largest that Solen makes in the axial version. There is also a metal can version of the PPE type, but they are larger and even more expensive.

The motor run cap is commonly used because of the price, as you can see.

Here's a guy in Florida who sells the aluminum can ones in several mfd
values but they may be larger in size than what you require.

I know regular capacitors can be wired in parallel to obtain a larger value.
I suspect the same should be true for a motor run capacitor but somebody
with more technical expertise can answer this.

Default Inexpensive motor run caps

I have NOT done business with this outfit, but they seem to have good prices on a variety of sizes of motor run caps

Yes, connecting them in parallel effectively sums their capacitance.
