DISCO 2 front bumper swap for facelift or disco 3?

what can go on as a disco series 2 front bumper as a replacement.mine is damaged and finding a standard series 2 bumper is difficult.does a disco 2 facelift bumper fit or even a disco 3 one and if so with what mods and difficulty.i ask as they seem easier and cheaper to find.
many thanks scottrover

Does any one know the answer to this?
