Sounds like a diff out of a late 1200 ute by the lenght. A series one bluebird will have a centre you can use or some vannetes as well as the 1200 ute. The axel will be specific to a 1200 ute and good luck with getting one only from a wrecker. But stranger things have happened...

Have both left and right rear quarters to suit 1200 sedans. Little rust at the bottom of each but pretty straight and free of bog, pretty sure its original pant so no hidden surprises. Cuts are still part of a rear half cut that starts under door opening, take as much or as little as you want.
Also have a rust free wheel well to suit a sedan also.
Pic up only, will cut off what you need.
100 bucks per quarter 50 for the wheel well or take the rear cut for 200, missing rear beaver panel.
