As many of you know, I have been hoarding parts for some time.
I am making a list of all parts as I find them.
Rear wheel bearings
The same as L80/100/200/500/700.
Rear stub axles will take different hubs.
Backing plates are welded on.
Rear brake shoes for L55 / L60 is 180x36mm making them the same diameter as later brakes but with 4x110 pcd and wide shoes.
Early rear drums have 10mm wheel studs, late rear drums have 12mm wheel studs.
Early 10 inch wheels fit over 12mm wheel studs, I have confirmed fitment.
Wheel hub / centre bore is 66.1mm
Late model wheel studs are 12x1.5 mm

This is from one source of the internet and I will do my best to cross reference for accuracy but the 4 speed information lines up with my printed chassis manual (with the exception of the final drive ratio which isn’t listed with the gear ratios).
L55/L60 with the AD engine has the dif ratio listed at 5.17:1
From my calculations the correct value of the diff ratio should be 5.7:1 . This is based of the site https://purperformance.com/p-29669-rpm-calculator.html with;
Speed 62 mph
Tyre diameter 19.09 inches (Falken fk07e tyre)
Diff ratio 5.7:1
4th gear ratio 0.971:1
Engine RPM 6039
This data lines up with the recorded speed I used to see when my car was running. I never had a GPS speedo to validate my data.
