Easter Weekend Overhaul: Advice Please!

[Kezzieboy]

BOOM! Was a bit if a faff, took some lateral thinking, but the whole arm which bolts to the boot floor splits from the beam, and then you can thread the beam through the brake pipes/cables. 

Rebuilt the rear end, brakes etc are back on. Moved onto the front, drivers side first, shock off fairly easy but getting them on took some force. Passenger side the same, but lost a little gearbox oil, will this be okay? It was a pretty small volume, and I guess it shouldn't make much difference. 

Only thing I can't figure out, how do you tell how far up the shock the upright should go? On both sides there are two different protrusions, one short one lower down, and a couple longer ones slightly higher up. 

On the pass side, the short one goes fits in the split in the upright, but this isn't the case on the drivers side. Does anyone know a sure fire way of getting it in the right place? 

Aside from that, suspension is done, just need to pop the exhaust back on again, and then it's ready for a test drive. After that if I have time I'll do oil and filter change, and some other odds and ends, but they can be done in Brum anyway.
