What's the smallest size that a Grubee engine tray can go to?

    I wonder can a Grubbe engine tray be made to fit a space of 155mm between inside of seat tube and inside of down tube. That is the space on the Felt Heritage just above the chain guard where the tray would have to go to fit the engine. If anyone has a Grubee tray not installed I would be very grateful for a measurement between the inside of the two aluminium blocks from tube recess to tube recess on the blocks themselves when the tray is fullu compressed.
