Big ride height change needed

Okay, I have radically altered my 74 dart swinger and taken about 300 lbs out of the front end with a new motor, 5 spd alumin transmission, and a glass hood. I need to lose 5 inches of front ride height. Is there any reasonaby priced way to do this? I am new to torsion bars and know they can easily be adjusted but that wont be enough.
