There is one minor issue with bonding the body after painting (that I can think of). The 427 body (and I assume 289 body) doesn't have the rocker panel flange any longer and the bottom of the rocker rivets to a tube at the outer edge of the chassis that secures it. If you rivet after paint you will either live with the unpainted rivet heads or touch them up in body color by brush. They are only visible down at the ground level with under car exhaust, or from underneath. Same thing at the upper inner roll of the grill - a couple more rivets.
