What are my chances of finding a 1993-shape 1KZ surf body/chassis in registered condition for a half decent price? I've been offered a complete, de-reg surf as part trade for a Safari, but it can't be re-regd due to having about $30k owing on it

And, given i'm not really dodgy enough to do a tag swap, i figure my only valid option is wreck it or swap everything into a good body. I don't need another offroad-only truck, that's for sure.
Most of the ones i've seen on TM are either wrecked, rolled, or 2L-T.
What d'you guys reckon i'd be looking to pay for a registered body?
Cheers
