I agree it is obvious what the seller's intention is, but why bother worrying about it? It is only a V8 GTS. and if I was a buyer of this as a modified street car I wouldn't give a rats if it was the original body shell or not. If it was a full on original resto and paying accordingly you'd go digging to check such stuff out, but as say a nice HQ street car with 350 and TH400 in non-original colour it wouldn't matter - it might as well be an original 173 3spd drum brake HQ Monaro body and tags or GTS tags on another GTS body.
