Help! Raising a flip kit.

[zigs74]

So here it is. I'm lookin @ lift shackles to bring the rear up some. LOL. Right now the rear is totally bottomed out on the shocks so it may even fall a bit lower if I were to remove them for drop shocks. I have about an inch from the rear axle to frame. Bump stops are totally removed. No c-notch. So far I hear lift shackles could give me about an 1" and the other option possibly new or heavier leafs. Not sure how much that could raise it but I'm sure my leafs are pretty worn since the previous owner used the Blazer for towing. BTW it's a 5-6" flip kit from western chassis.
