Message AutoEgo. He's not active on the forums but he is signed up and should get an e-mail if you messsage him. He's got guts from a few wheels lying around.
Try contacting Logitech support, they might be able to fix or get you parts, my G25 FF motor died after 3 years of daily use and they couldn't replace the wheel but gave me 50% off a new G27.
That's your personal issues, but that's how the real world works, Logitech makes a fantastic product and you're just shooting yourself in the foot for some personal matters that are unrealistically placed, it's how many company's work.
So your best bet is give Logitech a ring or prob. be SOL, especially if it were to break again mate.
It's not like Logitech's offices are full of G25 parts waiting to be thrown in an envelope and sent out unfortunately. The deal where they offer to sell you a replacement at half off is almost insanely generous IMO... I'd take them up on that (don't tell then you broke it, just tell them it broke!) then you have a whole G25's worth of parts to kit into something else sometime!
