The offside bracket rusted of so I took the rear box of and welded it back on. Rear box looks well grotty round the end welds so I think I need to replace it. Do I buy one from Merc or fit a bosal one or should I go for stainless. I like stainless but I know I will not have this car as long as the 940tdi (12 years) and exhaust never touched and still going strong. Any bright ideas out there. AA
