Series 3 Where next?

Ok, I've cleaned up the chassis, welded bits back on, filled any gaps and squirted nasty stuff inside. I've stripped the springs, cleaned and reassembled. I've stripped the hubs, cleaned and reassembled. I've replaced all brake shoes and cylinders.

Where next?
Logic suggests brake pipes.
Any other thoughts?

Engine and Gearbox then Bulkhead, steering, brake pipes etc and then wiring loom

As above, the last thing you want to do is ding the pipework putting the engine and gearbox back in

When you put the bolts in that steering relay remember to fit from the engine side.ie nuts at front .
I didn't and had a hell of a job to get the relay out a couple of years later.
