Torque box question

I just finished restoring my convertable. No rotisserie . 200K on the car. I put the last 100k on it and did not pamper this car .The factory door to quarter top gaps were too tight. Jack stands under control arms up front I put the rear stands under the front rear leaf spring perches and let the rear end hang to open the gap a little too wide.. I held my breath when I welded my connectors in. When I sat it down on all fours and my gap was perfect both side. Whew! Aside from that one time, I would always weld connectors with car sitting on the suspension.

That was pretty smart. Over the years, I'm sure they tend to flex both ends toward each other, as if to want to fold up. You reversed that and eliminated the possibility of it happening again.
