[Elecraft] K2 RF board X7-X11

[Conway Yee]

What is the best way to solder X7-X11 crystals?  The instructions say to
solder two ground leads on the side.  The ground leads on the left are
between the crystal and the resistor packs.

I think I should solder the ground leads onto the crystals before
soldering the leads onto the crystal case (at least on the left side if
not both).

Options?

tnx.
