a done this last year with a 2wd saph that had been smashed swapped every thing into a chassure shell, theres 3 things u can do really,

1, use ur id or buy a id and put that on to the shell then take it for a vic cheak so u hav all the rite docs to match the car,

2, use the new cars id and tell the insurance every mod and b stung by the huge premium,

3, just use the new cars id run about in it and forget about it,
