David Love asked:
"I presume you changed those to wrapped strings or something without
changing
the bridge. Did you use wrapped bichords or trichords, if you recall."

David,
You presume correctly. Wound Bi-chords. It is necessary to add 3 hitch
pins, equi-spaced, to make it work.<G> It's not the very best, but it does
make the piano resonably tunable and stable in that area. Of course, ya
have to warn the client that you'll be, somewhat, living with their piano,
forever, until the strings stabilize. Another issue is that the piano will
really go whacko, pitch-wise, when you remove the lower bass strings to do
the install of the hitch pins and strings! Be aware of it and it won't
freak you out ...too much.<G> Once the strings are on and the lower bass
strings have been re-installed and then tuned, it goes pretty much right
back to were it was before you started.
BTW, I try to avoid wound tri-chords if at all possible.<G> 
Best, 
Joe
