TVR Vixen 2500 bonnet replacement

hi all. at present i am working on a vixen 2500 for restoration. sadly the bonnet is in such a state that replacing it will be cheaper than repairing the thing. due to dodgy repairs after several crashes it weighs almost twice as much as the original and silly alterations / modifications have been done incorporating many pounds of (sheet)steel work.
can anyone of you point me to a (re)manufacturer?
your help is greatly appreciated. many thanks. i'm in the netherlands.
