Converting a 1995 G20 suspension to a G30?

Hi gang,
Anyone ever done this?
Making a 1/2 ton to a 1 ton?

I presume the parts are interchangable. :screwy:
I think I need to change the springs/shocks in the front.
1 ton front brake rotors and calipers

Rear axle with 1 ton brakes and leafs.

Am I missing anything?
Now to find these parts in a salvage yard.

Any thoughs, suggestions or concerns and expertise would really be appreciated!

Thanks,
