[Iver460]

I have several contacts who have done such conversions as it used to be a very common way to import new Gs to Norway for avoiding insane car taxes (you keep the original title). A lot of work is needed and my contacts usually charge about 100.000 Nkr (=12500€) and up for preparing a frame and mount a new car upon it.

Try www.autocenteret.no or contact me off list for another two contacts.
Oh, and if you want the car titled in Norway.....forget it. If you change the body mount location (which is nessecary from 460 to 463) taxes must be payed. Building a new 463 on an older 463 frame is still allowed and tax free.
