Hi to all the grey-market kubota lovers out there!

I have a problem with the PTO shift of my Kubota L2202DT. I had to open up the selector mechanism so as to repair a broken selector fork. I did that but couldn't get the whole thing back into the cavity, so I removed the two PTO widgets off their pins. I then got the selector plate successfully into the cavity and the gears work fine but can't get the PTO widgets back onto their pins, because the prongs that the widgets sit on (which are at the bottom of the cavity), leave the widgets sitting a little too high. I can't get the prongs to go down, or to move at all. What to do?

Thanks in advance!
