Was Unibody Strengthened for Convertibles?

I'd like to see that picture....curious...
okay here they are this is the back half of a 63-5 valiant convertible






I was supprised how big a chunk of metal was in there, I looked through a couple of oops spot welds that i went though on in the dart and it looks like it goes all the way to the front on mine the whole lenght of the rocker. betcha that's where the extra 100lbs are at
