I'm going to remove the rear seats and fit a fire wall (the plan is to have a swirl pot therefore a fire wall is required), so I need some suitable alloy sheet (can't afford carbon), I need a sheet big enough to do the job ie make the fire wall, with some left over for other stuff (heat shields, blanking plate etc) so probably looking at a sheet size of 1m X 3m anyone know where I can get some?
