Neil, if the "Z"-chassis doesn't show a damage/distortion underneath and is straight it shouldn't be too alarming in my opinion. Most of the part of the chassis where the crack is should be visible from outside of the car. To be on the safe side you could loosen the padding on the inside - if the owner allows. If the wood near the crack shows also no damage I would rate it as "cosmetical", probably badly repaired rust.
Worst case would be that the car had a shunt from the rear but then there should be other indications of repairs.
Good luck
Frank
