Need some help on how to lower this thing.

[OldJimmy57]

I am almost desperate to get this thing to sit down lower. Can you guys give me any ideas? Also the suspension is from a 1998 Corvette C5. It is actually a complete 98 C5 corvette drivetrain that has been welded to the 55-59 chevy truck frame. Am now I am kind of in the dark on how to lower it. The corvette guys said to get longer bolts and drop it like that. And I did but that puts the end of the leaf springs almost touching the ground. And a coilover setup for the corvette is 2300.00 I was thinking body drop but then the torque tube would be in the cab and in the bed. Any of you guys have any ideas?
