Terry, Baldwins can be fun.  If the wippens will work for all other 
parameters I have been known to take a pair of nippers and cut about half (or 
a little more) off the swedged end of the screw,  just make sure to leave 
enough for your regulation tool to get a bite on. So far this technique 
(albeit perhaps a little jackleg) has worked well,
though you might have to manipulate the hammer rail height to achieve a 
workable compromise there.
