I'm gonna do this as I've got a bent up shell but I think il try and keep the original catch just as personally I don't like the look of pins shouldn't be too hard by the looks of things just don't like the idea of risk warping it with weld.
Cheers stav, still got plenty to do yet but just moved into my first home so even more skint than I previously was and Ive actually been excited about making flat pack furniture.
