I have an issue with one of my guitars, and I want to hear your opinion on what to do about the matter. This is the case;
I've got 2 Tele's and a Strat (yeah, I know it's a Tele Forum) but this may as well be a Tele-problem since the issue is about the fretboard and the truss rod of a Fender AVRI and they're the same on both models. And I have a great confidence on your opinion, here at the Tele Forum, so don't throw me to the Strat-sharks, please!

Now then...
the guitar is an American Vintage '62 RI and I recently noticed that the truss rod no longer works as intended. I have no more options of adjusting the neck if I for instance would change to heavier strings. (I use .010-.046 on the Strat but I use .011-.052 on my Telecasters). To me it's kinda obvious that the truss has, for some reason, stopped working. Could be rust, for all I know. The neck is OK as it is, but there are no chance of straighten it anymore.
This axe is 10 years, and inside the case lies a nice little colorful note from You Know Who that claims "Lifetime Warranty" but one phone call clarified that it only applies in the United States.
Now I am facing some options and that's where you guys enters the stage: I want your best tip.
I could:
• Sell it and buy anything else.
No, not in this life. I will fix it and keep her 'til the day I die
• Send the neck to the US (StewMac or any other experienced "rod fixer")?
Quite expensive freight from Sweden and back!
• Buy, and install a new neck from a third party supplier – I have bought a wonderful neck from B.Hefner.
I'm leaning towards this…
• Try to remove the rosewood fret board myself, and install a new rod?
I presume I will have many a good advice from helpful friends…
OK, what would you do? Since You Know Who obviously won't fix it for free (Lifetime Warranty) I know this is gonna cost, but I'm kinda wailing what to do. And further more, these guitars are about $2.500 here so I wanna do what's best and cheapest in the long run.
