I don't know about export purposes but unless that part of the support is really bad, I'd try to keep it intact. The VIN stamped in it is important to some people for resale, even if it isn't a numbers matching car it. The VIN is only stamped two places that I know of, in the cowl and on that support. I doubt countries keep track of where VINs from every maker were stamped but you never know. Like me, you are replacing a majority of the metal on the car, but worst case I would cut that section out including the two holes and splice it into the new one if you are going to replace it. The upper support on mine is bowed, probably from a hit, but I'm going to do everything I can to make it straight.
