Interestingly, the Altair in question had two large caps in parallel
floating around in the case, tied to a card bracket with a twist-tie.
One of the previous owners must have replaced the original single
90,000uF cap with two.
$30 later from Mouser, I bought a single Sprague 100,000uF/40v cap to
replace the two and bolted it into the existing 3" bracket.
Original? No, but neither was the earlier repair. At least it fits in
the mounting bracket and exceeds the original specs.

I take issue on some things like cutting holes or like
a recent post
I try not to make holes larger than screw holes (for sensibly-sized
screws). But if I have to replace, say, a transformer and the new one is
not idetnical to the old, I'd rather drill an extra mounting hole or 2
than leave that transformer hanging on one screw.
removing a large filter cap and replacing it with two
smaller caps,
even
If the original filter cap is unavailable, then I would replace it with
2
smaller ones in parallel (better than having a non-working machine,
surely). I'd use the right part if I could get it though.
changing screws when you still have the originals.
Let's not start that again...
