I know how i want to lift it, and thats what im going to do, how it turns out, is how its gonna be.

Now back to the car
Question

Is it possible to reset parabolic springs?

I have the engine, (pix lata)
New 1HZ out of an 06 100 series.

Now do i need the complete wiring harness or do i only need the harness downstream from the computer?

Will the 75 series harness work?

Do i need the computer from the 100s or from a 79s with the same engine!?

So many questions!

The springs will be the make or break issue in the SOA. I would forget the notion of using reset worn out springs.
I would see Dean at Malaga Suspension or maybe West Coast Springs in Ashfield and get some purpose built springs suitable for SOA.

I think the high arched springs look crap and for the reasons Crushers outlined will not flex too well.SEE BELOW(not too bad but could be a little lower,I think its in Darwin)
The SOA with flattish springs will still have a good sized lift .
I would leave the double hinged shackles alone until the SOA is complete and fully test driven

You do know the cops will put a SOA vehicle off the road as soon as they see it?

The computer doesnt do much if anything on the 1HZ as far as I know.

The cruisers with the 1HD FTE do have some(LOTS) electronics.
For your purposes I would study the electrical schematic in the FSM and get the engine set up like a early 90s 1HZ with just one wire to the fuel cut solenoid.
