[Elecraft] [K2] Order of installation of Options

[Don]

Just finished and aligned my base K2 and everything works great. I am 
currently building the options I want, and will finish all and then will 
proceed to put them into the K2 all at once.

Question=> What is the best order to install these options, from both an 
alignment (will use Spectrogram on next alignment once these are in) and 
ease of installation point of view. The options I will be installing are 
as follows:

KAT2 (nearly finished)
KNB2
K160RX
KAF2
KI02
KSB2 (possibly..not sure about this one...I am a CW op primarily and 
RARELY pick up a Mic, but do occasionally)

Thanks,
Don KF7DS
