Well picked up a whole Datsun 1600 rear end tonight, diff drive shafts moustache bar and irs arms.

With my Spare bw diff I can use the measure ments as a dummy set up. Also have spare leaves to dummy up to the same diff.

All I need to do is make a rear bar to simulate the de Dion bar. Also think I have the mounts sorted for the diff.

6mm plate top and bottom of the passenger floor,metal and space the diff to the right height with high tensile bolts and crush tube spacers.

Rear the moustache bar will mount to a 1inch square length if box steel between the chassis rails with plate on top of the sheet metal in boot.

Will dummy it all up as bolt in and sleeves, then just weld ut all up.

Also had a tip to fill the de Dion tube or bar set up with 2 pak foam. Light when cured but doubles the torsional rigidity of the set up.

If I get this to work can then.look at rear disks and Subaru viscous LSD.

At least as bolt in so far it's all easily put back to current set up.
