Best Handling Bang For Buck?

[ShortCST]

In a few hours, the 15% sale at Hotchkis will be over. So with a little bit of cash in my pocket, I'm considering options to make my truck safer. Disc brakes is one consideration for my '68 short fleet (factory drums all around), and so are chassis/suspension mods.

I love the look of my mostly stock survivor, so if I were going to lower the center of gravity at all, I would be looking at maybe the 1.875" drop Hotchkis Springs in front, and some 2" springs out back.

Would sway bars give me a better improvement in cornering/handling? I have a solid sway bar up front (Early Classic, iirc). I don't feel like it did a whole lot for me.
