MK3 to Mk3s Upgrade

hi all.  Had upgrade ready for a while now and just about to perform the steps to complete this.  I have printed the plastic parts from the Prusa files as per the instructions.

My concern is the fact that when the extruder is fully assembled the V6 hot end has some significant play/movement on the Y-axis.  The Mk3 plastic parts held the V6 hotend tight and there was no movement at all.  Should I be concerned?  it seems to me that I should as movement will surely spoil the accuracy of the layers.

I would appreciate some advice as to what to do to fix this.

Hi John, 
if all screws are tight, and you still have movement then it's not good, 

try wrapping a bit of tape around the locating boss on the heatsink at the top, where the extruder front and back should clamp the boss.
