    There should be two long bolts 6x18mm to accommodate the overflow tube brackets on top and two short 6x15mm for the bottom.

  6. Re: Removing paint on aluminium panels by sanding or with selected paint stripper

    Use a stripper whose main ingredient is methylene chloride. Best to use outside or with ample ventilation. Don’t use a stripper containing sodium hydroxide as it will react with aluminum.
