Dave:
 
Are you willing to mortise out the rail and glue up a new piece  of wood, 
the re-drill? You'd have to make a very precise template of the  keypin 
positions indexed to the frame. It's not all that difficult if you have  the 
right tools, but the definition of "major operation" varies with  experience and 
tooling.

I’m rebuilding  a Baldwin R and on removing the corroded and pitted key 
pins, I discovered  that the base of the guide rail pins are 0.177”.  The top 
(swaged) part  is a standard 0.146” but the part that is driven in the key 
frame is  oversized.  Of course no one has replacement pins like this so I’m 
going  to have to make some modifications. 
Everything  that I’ve thought of so far has looked like a major operation, 
and will leave  lots of opportunity for errors.  Has anyone run into this 
before?   What did you do?
