Do you have the mod that allows for swapping the antenna inputs? This

I haven't yet had the guts to attempt this, simple as it is. To say I
am klutz with a soldering iron would be understating it badly. Also,
it sounds as though it is useful to use coax cable internally to
provide the electrical hookups, and I have not yet figured out the
optimum way to do this (a *good* picture would help immensely!).

Otherwise, it sounds like it requires just a simple DPDT toggle or
similar switch mounted somewhere, with the two antenna leads attached
to each pole at one end, criss - crossed to the other end, and with the
two main/aux leads connected to the middle posts respectively - is that
about it? There is no need to do any ground connections, since the
whole chassis is grounded...

How hard can that be? ;-)
