Starting to wonder if I should put these in my USA fender... No must resist! I had an sq series squier until recently that I sold in a fit of madness. It would have been perfect as it had been pretty molested by the previous owner anyway.
I know what you're saying BRX, but a Lull is out of the question, I'm not gonna buy a t-bird as I'm scared of the ergonomics not suiting me (and they're a bit too "look at me!") and, as pointed out, the thunderbuckers are probably the cheapest t-bird style pickups while still seeming to be excellent quality. May be worth more than the bass I would end up putting them in, but it wouldn't be the first time!
I'd probably do the unthinkable and have a rattle at modding the donor bass myself to fit the pickups.
