Modern saddle needed for old-school Schwinn seatpost...

Guys and gals;

I’m dying over here! Resurrecting my 24" for some unicycle polo (been livin on the 36’er for months) and just tried to save my circa-1985 Schwinn saddle by restuffing it with material from an old car seat (horsehair! No kidding).

Needless to say, my normally well-behaved sitting area is complaining loudly, and I have to do something.

So… looking for a saddle that will fit the 4-bolt pattern from an old Schwinn seat post. (It’s a smaller pattern than the more modern ones). Anybody have something that’s relatively modern (gel, air, or just good quality)?
