i spent 2hours readin the entire manual and it doesn't specifically saywhat you can and cant do, it says for a pass the car must score 8/14 identification points, it states that to score these points the replacement parts have to be either completely original or rebuilt from parts from 1 other donor car, so for exampl, if i swap out Orion floors, crossmembers engine transmission for sierra bits converting it to rear wheel drive along the way using sierra shell or 'monocoque' as it calls it in the manual..does this mean i will be able to keep my cars identity or will it be q plated regardless
