[Elecraft] K2 upgrade question

[penzo@juno.com]

While looking through the documentation for upgrading my K2 A to B, I
noticed mod number 7, Second Crystal Filter Flatness.  I also noticed
that the upgrade kit is part # XFILMDKT and costs $10.

Is this upgrade kit the same mod titled: "K2 2nd Stage Xfil Mod, for
'Flatter' SSB Filter Response" with the procedure and parts packaged
together?  In other words, if I've already performed this mod from
on-hand parts, can I save my $10 and check mod number 7 complete?
73,
Mike
