Where to find springs/lift kit for '79?

[zac]

I'm not so much of a lifted truck kind of guy, but I think my tire selection is going to require me to at least get my K20 back to stock height if not a little higher (possibly 33x12.50 16.5's). Maybe an add-a-leaf or leveling kit? Of course my truck appears to have been through hell and half of Texas, so it probably needs springs all the way around. Either way, I'm not seeing products for this truck real obviously displayed on the websites of the usual suspects--Rancho, Skyjacker, etc. Do I need to look harder, or somewhere else altogether?

Never mind, I found a bunch of stuff. How about the add-a-leaf deal? Is it a decent option?

Add-a-Leafs are known to sag. They get the job done, make it right rougher, and will sag.
New complete leaf packs are the way to go... but may not be the most cost effective.
You could go with blocks in the rear, but they cause axle-wrap.
A good way to lift the back is with a shackle flip (Offroad Design, or DIY4x4)..
The front would be best with new leaf packs as blocks are a no-no on the front.

Cost wise add-a-leafs would be the way to go but if you want to do it right and spare some coin a new spring pack is definitely the way to go.
