I don't exactly what kind you're looking, but I have come across a few fics where Bucky never kills Howard. But they are mostly centered around Steve/Bucky with Tony basically being an epilogue sub-plot.
1) The Silver Age by Copperbadge http://archiveofourown.org/series/353996
An alternate universe in which Tony Stark was born in 1950 and the Winter Soldier was recovered in 1967, after a failed attempt to assassinate Howard and Maria Stark.
2) We are kings by Hey_Diddle_Diddle25 http://archiveofourown.org/series/527791
alternatively Howard Stark gets a second chance at parenting and the world is certainly not going to make it easy for him.
