I have finally got it off, one of the bolts came out after being soaked in Plus gas and being bashed with a small cold chisel, the other one started to turn after the same treatment and then snapped, flush with the head when I got a torx bit hammered in it So now it needs drilling out and re tapping........simple? yeah right Think I'll take it to Del Basso's, and let them have the fun. Thanks to every one for the advice. Nick
