bolted

Is the W124 Mercedes Star bolted on the same as the W126? I don’t want to remove the carpet if it’s just stuck on but then I don’t want to brake it either :)

Are the w124 wings bolted or spot welded/any other kind of welding on?? I have rusting nearside front wheel arch that I want to replace as the blistering has almost gone right through, would I be better getting main stealer/Merc specialist to do it or have a go myself ? :confused: Cheers...
