Difference between K5 and K10 Blazer

[JDSurge]

Speaking of stock springs, it looks like the front should be just 2 springs so I'll remove the bottom spring to get it back to stock. As for the rear, does anyone have any pics of a stock rear spring set up? Or how many springs should be in the rear? I looked at a spring site and they showed the 2 leafs in the front but the minimum springs they show in the rear are 5/1, which mine has so if I took out 1 of the lower springs, it should lower it about 2" maybe?
I would like to lower the whole thing about 2-3" if I can. Too old to jump up in it anymore.
