68 Stepper Stance Help!

[68Stepper]

I'm looking at 3/5 springs, shocks, and an adjustable trackbar/panhard bar to install on my truck. Feel free to throw any recommendations out there but I'm leaning towards CPP stuff. I understand that the ride could suffer and may have alignment issues, but I'm not willing to do spindles and do the spindles/5 lug/power brake conversion just yet especially when I'm only driving the truck 3000-5000 miles a year.

At the same time I lower it, I'm also looking to purchase 2 Wheel Vintques 15x8s steelies for the rear, and use them in conjunction with the front original 15x6s.

I REALLY want a stance like the green 68 pictured below. Does anyone happen to know whose truck this is? I'd like to confirm the rears are 265/70/15s and try and get some other options/opinions for front tire sizes.

Thanks!
