What makes you think the front has sunk by 70mm????
ALL ute/commercial variants of most makes all have the rear higher than the front even when new. You probably cannot determine the amount by measuring the bodywork at the rear and the front of the sills. It isn't a car and never will be.
Perhaps research the vehicle
suspension system specs to see what the front bump rubber clearance should be/was when new. A 2011 Dmax is 29mm gap there just for example. A Mitsubishi dealer should have those specs or an online workshop manual. It seems the Delica runs almost the same
suspension so that is a source of what is real.
Your
suspension uses a larger upper ball joint, as that is required to take the vehicle weight via the torsion bars and upper arm to the stub axle assembly.ie , holds the wheel down so the vehicle is held up.
I am not sure looking at videos will help much, I know they are popular but they are a bit like 4wd magazines. Having a knowledge of the
suspension layout through reading and inspecting workshop manuals related to the issue will assist in understanding with what mods you may you want.
Still factor in good shocks though, because they allow the control of any mod, ride height, increased mass and assist in ensuring the life of wheel bearings, ball joints,
suspension bushes tyres and steering.
You said in your opening line,"different shops say different things", because almost all of them are not mechanics and have little understanding of the concepts they sell, simply sales staff. Only a few know what they are doing. It is about sales, not you at all. The only reason they get it right is if it is fitted correctly and the unseen engineers who gathered together the items for the so called "product" actually know something. Even some of those have been found incorrect.
