Rubbish. Peel off the rubber seal in the rail and there are screws holding on the hood. Remove those and the bolts holding the corner brackets & then it can be rewelded. MMC are parsimomious with their weld. Get both sides fully welded not just spot welded. I fitted a new rubber seal on reassembly.
That's the best word of the day "parsimomious" 🙂
