Vic and friends,  The easiest solution would be to tube the tracker
and stack to play the 125 rolls and make an adapter in order to chuck
the rolls onto shorter width of the frame.  The hole spacing is the
same so the extra holes at the end would be not used and blocked off.

If the roll frame is of Wurlitzer design, the bars can be shortened but
a new tracker bar would need to be made.  It would be much easier to
swap the tracker bar than the chest and pipe work.  This would work
best if the builder has not already invested in Style 150 rolls.
