Rear Suspension question. Drop spring or combo of spring & block?

[1964FarmFreshC10]

Howdy folks.

I’m currently installing 2.5” drop spindles and 1” drop springs on the front of my ’64 C10, for a total front drop of 3.5”. I’ve already picked up CPP tubular trailing arms for the rear, but I haven’t ordered the rear springs yet.

From what I’ve read and been advised, with a 3.5” drop up front, I should be aiming for around a 5” drop in the rear to achieve a proper stance.

My original plan was to go with a straight 5” drop coil, but I’ve recently come across recommendations suggesting a combination of drop springs and lowering blocks instead.

I’d appreciate your thoughts on the best approach.
