Whats the best way to lower w/leafs

[jott_06]

I have a 68 GMC 1500 and i'd like to lower it but i dont want airbags or anything like that. I was wandering how low it would put my rearend if i c-notched the frame and did a axle flip. I also wandered if anyone has ever used the rear lowering shackles and how they liked them. I will probably just go with shorter coils on the front. I thought about cutting them but everyone seems to think thats not safe. I ran my s-10 with a rap cut off of the coils for along time and it didnt ride ruff or anything. But i just need some info if anyone can help me...thanks
