69 c10 crown vic frame

[Dupes]

Anybody ever do a body drop on a c10? Was looking around at the metal shop and they had 2 x 6 square tuning on sale so I picked up a few lengths. Plan is to move the frame in around 3" and down. Going to take the springs out to see how far down I have to make my new frame so I can slam it down. But...then I have to drop the body down to cover the new frame. The pan is rusted out in all 4 corners and well as around the rockers so it will have to replaced anyway. This should be fun.
