Gen 4 springs on a Gen 3

I'm interested to know how the Gen 4 suspension springs compare to those on a Gen 3. Can anyone shed some light? I'm sure they will physically fit but a side by side comparison, or information such as the number of coils, wire thickness and free lengths would be great. Does the Gen 4 still have handed springs on the back?
With everyone opting to immediately ditch the standard suspension on their new Jimny's I'm wondering how my older one would sit on some nearly new springs.

They are not handed apparently and when I did the maths they worked out giving a standard jimny approximately 30mm extra height. What that will be in reality is probably less I would think.

One of the last 200ish of the gen3s, probably.

Gen4 springs are definitely handed. There's 15mm more preload on the drivers side and two different part numbers for the rear. Fronts are not handed and same part number left and right.
Springs do fit in a gen3, they are a smidge higher spring rate front and rear but otherwise will fit.

Sounds like a perfect cheap upgrade to my ageing gen 3 suspension. Thank you.
