If so don't cut the skin and the bracing at the same place.
Tacking and checking on the car seems the way to go for sure.
What welding method are you using?
Yep, there is bracing. I would leave that in place and just take the skin off. I am using wire feed flux core...........I know gas is better but I have welded patches on the quarters and metal part of dash w/no warping. I just take my time and make tons of little welds and rotate around as to spread the heat.....seems to work for me.
