[Elecraft] K2 options

[Ronald Lawson]

I've recently completed a K2 assembly and have on order a couple of options
for it.  I also have some plans for some modifications beyond that.  Is
there a library of current option "footprints", like option pcb dimensions
& mounting holes, such that modifications can be included without
interfering with custom work?  There are a few things that I intend with
this little bugger, I don't want to preclude future option installations.
If I had a well dimensioned pcb diagram showing mounting holes and
interface connectors for the various factory options I'd have a picture of
what I can and can't do inside this box.
