Kjeld,
I admire your spirit, but honestly think you should be looking for another wrecked car and use one of the two as the donor. It will probably work out cheaper than trying to find and purchase parts piecemeal, shipping etc.
For example Beverley Hills Car Club had this car reduced to around $15,000 over Christmas and they do seem to get low end cars with parts missing with regularity. Something like this could provide most of what you need or vise versa.

Also contact Larry Stock at Pantera Parts Connection in Carson City NV, he had two or three wrecked Pantera bodies he was slowly stripping sheet metal off of. Prices are not likely to be cheap though.
Good luck,
Julian
