I'm having a heck of a time finding the 74S01 and 74S73.
As far as I can tell from the data sheets, the 74S103 is functionally
and pin-compatible with the 74S73, but a little faster. I wouldn't mind
substituting that, but it doesn't seem any easier to find.
The 74S03 and 74S107 are non-pin-compatible replacements for the 74S01
and 74S73, but I'd much prefer to stick with pin-compatible parts.
Unicorn Electronics can get all of those ICs, but you'll have to
order a minimum quantity.

None of them (other than the 74S03, which has the wrong pinout) are
listed on their web site. If you mean that they can deal with parts
brokers at my request, I've tried dealing with the parts brokers
myself, and had poor results. I'm willing to place an order for $250
total, but not for $250 for each line item, which seems to be the
minimum the brokers are willing to consider.
