I'll have to bend the front panel forward into place and the top cover has an interesting S curve in it that will take some figuring to correct - I think I'll use a hunk of 4X4 plus some other lumber as a forming block.

I have a gutted transmitter I can use as a donor, but how do you get the antenna terminal off without using tin snips and destroying the front face?  And how do you get new one back on the set to be repaired?  I can make a reinforcement plate if the hole is too big and rivet it into place using real aircraft rivets and add a note that says "certified as original by Mike Hanz" but how does it fit on there?

First, my condolences.  It is always amazing to me how many folks ship 
these radios without thinking of the "high points" and suitably 
cushioning them, but that's neither here nor there at this point.

If I understand you correctly, the force has pushed the antenna terminal 
inward, breaking the insulator and flaring the hole, sort of like a 
female engine fuel line.  If the front ceramic insulator is broken, 
can't you just push the terminal all the way through now?  The only 
thing inside the transmitter that might be interfering is the antenna 
relay, and that pops off with two screws.

As to eliminating the flare damage, all you really need is to press the 
inward flare down flat again (once you have removed the terminal, of 
course :-) ). As long as there was no tearing of the aluminum, then you 
shouldn't need a reinforcement plate.  The new terminal should fit right 
back in after the aluminum repair.

Heh...decals of "certified as original by Mike Hanz" are allegedly 
available on ebay, but I dunno how much that buys you.
