I would just remove the front and rear springs and lower it down on jack stands.
I'm pretty sure those 9.5's up front are going to keep you from going very low. The back should be fine.
How low do you want to go?

I was thinking 2.5 spindle in the front and 4" coil out back but before I drop it I am moving the fuel tank to the rear how much will this effect the drop? Gas on averagre is 6 lbs per gallon most tanks are 21 gallons ?
