Lowering a C30

[Rexroth]

Hey guys, been a lurker for a while over on the 88-98 board, but I've now come across a deal on a 1960 C30 stepside lwb. It's a pretty cool looking truck, and definitely not something you would see driving around where I live! I'm a big fan of lowering a truck, especially the bigger trucks but I can't seem to find much about how to do so for this particular model.

I figure I can just crank the torsion keys and lower the front, but I'm scratching my head for the rear. Ideally, I'd like to flip the axle but then what do I do about notching the frame? Would I be able to use a c-notch from a C10/20? Course, push comes to shove I could always take it to a shop with a fat wad of cash but I do enjoy learning how to do things myself. Heck, I had never changed the oil on a car before I bought my GMT400 two years ago and just last month I finished an engine swap on it.

I've searched the web, but maybe I'm missing something..
