I went out and got a slightly-used newer seat from a used bike, tore off the cover, and carved the foam with a serrated bread knife to fit my butt (and my wife's...). Then I made a nice Naugahyde cover for it (those poor Naughas...), added 1/2" batting over everything and riveted the cover down onto a stock seat pan, so I could keep the keylock and such. That was 15 years ago, still looks and rides great! And, it fits just me (Aaahhh...)
