[Elecraft] K2: K2KSB2XTLS installation question

[John Shadle]

Hi,
I'm trying to finish up my K2 and am preparing to install the
K2KSB2XTLS mod. I understand where these crystals go on the KSB2
board, but am trying to figure out which crystals I remove from the RF
board. Looks like probably X7-X11, but that leaves me with 2 extra
crystals for the RF board. Where do they go?

Thanks in advance.
