Hi Jason,

Attached is a picture and a drawing I made of the hollow aluminum rods
that activate the pushrods that push on the keys.  I'll see if I can
find more pictures.  The hollow rods are positioned (as I recall) at
about a 45 degree angle when at rest.  In my mind, I see the distance
between the end of the rod and the center section of the rod as being
1/2",  maybe 5/8", but not 3/4".

Sorry I don't have more to offer ... yet.

Musically,

    [The picture and drawing John refers to was forwarded to Jason sep-
    [arately.  Robbie may post them to the MMD Gallery on his return.
