The loose bits I saw were a pin about 10mm in dia. and 20mm long. This was located in the axle tube and popped out when the old bearing as being removed.
I think the new diff is a Borg Warner - at this stage I cannot tell you for sure. I will know the model number and full details in a week or so.
The axle was too wide and had to be shortened as did the drive shaft from the gearbox. The old brackets for attaching the damper to the axle had to be cut off the old axle and re-welded onto the new.
I only have the single circuit brake system and no proportional valve - looks like they got lucky with the relative differences of slave cylinder sizes - the braking is 100% better than the old drum brake.
Peculiarly, prior to the new diff/axle, the ride and handling was hideous. I was planning on changing out the springs, dampers etc to fix the problem. Now, its smooth as silk and is much more stable. No suspension components were changed or serviced. I have no idea why the improvement is so drastic.
