Pros and Con's of remvoving the body from the frame

o ok thanks,

my bad 8)

Im 34 and still ask tons of questions on this site. And in regards to your question Ive read in magazines guys doing "frame off" restorations on mopars and i thought hmmmmmmm, how could they do that if its a unitbody? Some of them i think did remove the "frame" and use an art morrison frame, but others made no mention of a new "frame".
