Finished off the rear end before going away on holiday next week, happy with progress.

Sorted the missing washers after hearing back from Derek, along with the a-frame bolt issue. Then lined up the a-frame with the recommended 3 washers on one side and 4 on the other.

Then levered the un-needed flanges from the diff to put the driveshafts in, and built up the ears/hubs/discs, finishing by getting the hub nuts as tight as possible by hand with the car in the air.
