It looks like I will have to find an equivalent product that works with the 4Runner/Hilux Surf. It looks like FJ Cruiser parts should work, I see a few threads here about FJ springs.
I understand you guy won't be able to say for sure - you might not even know of these brands.
But what I would appreciate is any suggestions of questions to ask the supplier.
This is the kit I was thinking of - the whole lot - shocks, springs, mounts, upper arms. I will go with firm rear shocks and springs as it is a working truck, carrying tools.
