Hope you find it, its like loosing your sight ain't it!..Do you know where the local fly tippers go, try looking for bits there, or in the local weighing in place. If the worst case try looking on ebay in a few weeks,for bits.
Years ago we found the cutup chassis of a mates nicked landy in a ditch, and later the engine/ box on e bay... and they had bits of it at there lock up,,,,They where very sorry and made a VERY generous compensation gesture,when asks NICELY!BY A FEW MATES...
