Flip kit after 4" lowering kit?

[Dirty_Hairy]

I just picked up a 93 C1500 Sport and I wanted to lower it so I went with Belltech 2-3/4 lowering kit with the coil springs and I like the look but I think I want it lower, how can I put in a flip kit now that the springs have been lowered 4"? I assume a flip kit by itself gives you 6" and if it is already 4" with springs then 10" would be way too much. My original spring perches are a bit beat up from chiseling the rivets out and the truck came with 2" rear drop shackles so I do not have the factory ones.

Thanks for any input.
