If it is of any interest, we have had a GTO Replica in our Workshops for a few months, being finished & sorted for the Owner. We didn't build this one, but it is quite a tidy beast with the correct Borrani-style wheels and a Cream leather interior.
It does really look the business, and would fool most passers-by into thinking it's the real thing.
We did a lot of research into the Kit(s) available in the States some two or three years ago, and it boils down to around $4,000 Dollars for all the GRP panels to convert your 240Z/260Z, plus costs of shipping, about the £1,000 - mark. Then you have to give the Customs man a slice equivalent to the VAT on the total costs so far.... and you have to buy a Restorable 'Z' to build it all onto.
This gives you all the outer skin panels to replace the steel 'Z' ones, but of course you have to Restore the basic Bodyshell ( i.e. the Carcase ), first of all. A decent Panelbeater could do a good job of fitting the GTO panels, but unless you are very good with Bodywork, it is not recommended to do so yourself.
When you pay all the Labour, the finishing & Painting, etc., and buy the correct wheels and other trim parts, you will be into the £20K region as a minimum. And that's without any tuning parts or any performance stuff like triple Webers, etc, which are a must for this kind of car.
If anyone is serious about doing one, they are welcome to visit us by appointment to look over this one.
It will be for Sale in the coming Spring, but the Owner is looking for the same kind of money as the one in the recent Auction fetched.
