[Elecraft] K2 - grounding of RCVR filter Xtals

[ON4WIX]

Hi all

My K2 s/n 5361 is coming together nicely, up to now I've encountered no problems whatsoever.
I just installed the receiver filter Xtals X7 through X11 and now I've arrived at the point where these Xtals have to be grounded (page 53, last step).
The manual states that a special grounding technique is required for the grounding of X7-X11. Instead of soldering a grounding lead to the top of the Xtal housings the manual states that the grounding wires need to be soldered to the sides of the housings.
There are 2 grounding pads for each Xtal. My question is: is it absolutely imperative to use 2 grounding leads for each Xtal? I don't see too many problems soldering the leads near the outer edge of the PC board, but the soldering points at the opposite sides of the housings are awfully close to RP4 and RP5...
Any suggestions as to how I should go about soldering the grounding leads at those sides of the Xtal housings?

Thanks for any advice.
