Seeking input lowered rear end 1986 c10

[Goats86]

Looking for new ideas. I "flipped" the rear end under my c10. As it is, it is lower than I care for. That said, Any ideas to get a 2 1/2" to 3 " drop from stock? I cannot do longer shackles as I have a Blazer tank and the fill tube would cause interference. An idea that I would like input on is raising the front spring mounts, leave the rear shackles stock and reweld the perches to correct pinion angle. Has anyone tried that? If so what kind of drop did you get? OR can I get new leaf springs with less arch? If so, do you know who sells them? I am cheap and would like to keep it that way.Thank you in advance for any input!
