I have to agree with the spring in the back. I built a 31 Coupe with the
stock spring over the axle (57 chevy) I spent a lot of time having the spring shortened
'eyes reversed, and rerolled. Ended up with 4 leaves in the spring. This was
with a 4" channel. It could be done by Zing the rear frame, now you need to
modify the body sub frame.
