Rear suspension is

Standard width 8 3/4 axle
Hotchkis leaf springs and shackles
Hotchkis sway bar
Hotchkis adjustable shocks
Dr Diff disc brake kit

I did have 1.5" lowering blocks in there , but the driveshaft would contact the tunnel near the rear yoke.

I only finished building the car in August, so there's still some development to do.

Jobs for the winter:
Raise the tunnel a little and reinstall lowering blocks
test with grippier tyres and install panhard rod / watts linkage if necessary
install some anti-tramp shocks or links on the axle.
