Stock Height suspension suggestions

[68ls1]

So I'm building a 71 4WD Blazer, probably my retirement project. So to put in context this is a fun vehicle, that I can go visit friends, or have a road trip. Most of these will involve miles of highway driving. Then have the ability to sneak off road to light trails or the beach. I am located in Australia so planning is essential as shipping is a killer

So plan is to stay around stock height, with 17" rims and 285/70 tires.
Upgraded steering box. I went with Blue-Top, customer service was first class

I am looking for shock recommendations, I think I found a KYB solution that is about improved highway manners, Gas-A-Just
