Newbie tech is the perfect place for this.

OP: with 35s, youll want 5.29s

Your looking for any 63 inch chevy spring. Used on most half tons from the 90s through the mid 2000s.

Look for any marking or numbers on the springs to try and identify them.

What are you trying to achieve out of the shackle? Lift? What wrong with the ones that are on there.

If you leave the front diff open the stock shafts will hold for a while. But if you lock it, be ready to buy some Dirty 30s or Longfields.

No Idea on the engine swap, we dont have holdens over here.

Might also want to look into a IFS steering box and Histeer.

Welcome to the forum!

5.29's would be good

2. what Chevy springs do you use or whats the best year model ones to use

90's 2WD springs will work.

3. it looks like it has a lift kit in it but he doesn't no what no one it is how could i find out?

dont know... sorry.

4. are rancho shocks good for general rock crawling

rancho's will be fine.

5. buy or make my own shackles

up to you, if you can make them all the same and get ahould of good meterial your golden.

6. if i were to change the engine out and i was going to put a Holden commadore engine in should i use the auto transmission or use the hilux one and are stronger cvs needed atm or only later on im only going to do abit or rock crawling.

up to you. if you use the GM tranny the 5.29 gears might need changed.

im sure i will think of more

when you do let us know..

In theory, it will flex better. But will also be more prone to bent leaves, and might cause the truck to sit lower.

Might want to look into different shackles.
