Thanks people!
Besides gassing myself with the number of holes I had to cut in the body to clear stuff, and wearing ear muffs, it steers fine with no PAS and rides awesomely. Just need to make a front shaft up and cut the rust out of the foot wells and mount the twin sticks again. I'm not happy with them between the seats.
Going to fit one of these:

This will get rid of the OE heaterbox and give me A/C at the same time. An added benefit is that it uses the same motor for both, which is not that waste of space OE one, but a proper wind in your face fan. I'm going to hide it where the glove box is, slightly inboard of that.
1 vent permanently to the demister
1 vent to the rear passengers
1 vent to the feet
1 vent to the body.
Going to use something like eyeball vents and a custom centre console (if I can get a bloody Art Carr shifter... how hard is it to get a quote to ship to Oz???) to get the rear passenger vent.
Switches will be replaced with OE knobs in the OE position. Will probably make the demister and vent pulls into possibly a rear demister (slimline fan or electrical strips) and possibly even a rear window wipe, if I can find a small enough throw.
Might try to bleed the brakes again and take it up to the exhaust shop today.
