[Elecraft] Installing Mod kits?

[Bill Maddock]

 Guys,
 
    I have K3 SN # 1059 and plan to install all the mods
short of the new DSP board! My radio doesn't have the sub reciever
so several don't count.   I have 2 AF output mods, and have been
wondering if one doesn't supercede the other. They are 
 
  AFOPMDKT - K3 AF OUTPUT MOD KIT
 
  K3AFMDKT  -  K3  AUDIO LINE OUT MOD KIT  This one seems newer?
 
I have had these for a while and have procrastinated. Now is good time
with 1/2" of ice on all my antennas from storm that passed through
yesterday!
 
  Thanks for your time,

ps: sure hope the radio works when I'm done!
