I am sure the factory won't complain about you having removed the socks - and this, to me, is absolutely what you need to do to determine the full extent of the water damage.
Be aware though that it may not turn out that "the worst involves a little cleanup and soldering". Possibly, the glue has failed and the wiring has lifted off the mylar?
Please post some pics and a description of what you see, when you've done this - we may be able to provide some useful advice.
How far you want to go of course depends on:
* how much you love their sound (or what you remember of it! ;-)) ), and
* how deep your pockets are!
For instance, if the MDF/chipboard frames are ruined down the bottom because they absorbed water ... it would seem to me to be a good idea to have the original frames replaced by hardwood frames (rather than simply getting new MDF/chipboard frames). But that will cost more.

OK, then it looks like de-socking is the next order of business. Looking into the cavity where the terminal strip wires exit for parts unknown, there is no visible water damage to the MDF; nor does it feel misshapen or swollen at the corners of the panels, so I remain hopeful.
At this point, I can afford to have a repair done by the factory, if necessary. I'll see if I can "undress" one of the afflicted panels and scope it out.
The terminal strip is in the tweeter panel if I remember correctly, and so is the crossover, right?
Don't really know if the XO is in the tweeter panel but that is where the space is so that is very likely.
If you intend to send it off to magnepan then don't bother taking the socks off and just do so. Your measurements already indicate that some wire repair is necessary on the drivers. Moisture is very hard on the wiring. Mind you that the tweeter repair is difficult since it is a push pull design so has magnets on both sides.
If you feel comfortable doing the wire replacement yourself then order the wires from magnepan and go do it. It is time consuming and tedious and you need space where you can use significant quantities of acetone without inhalation or fire problems.
Sorry, don't know. I only have experience of T-1Ds owned by my friend.
