7 inch rear drop pics???

[bdydrp97s10]

i know its been asked but after a quick search i cant find what i want..

i have a 68 a c10 that has heated coils in the back that the PO did..

i dont know how much he lowered it, but i want to buy new springs for the rear.

i now have a 2" block in the back with the heated springs but it still sits too high for me..

so i need pics of a 6 or 7 inch drop in the rear so i have an idea of what spring to buy.

axle to frame clearance pics would be helpful too
