My bro did one of the local lads Jamies Disco. They did it together not too long back. Came out quite nicley.
will add pics:
Looks better now it has some finishing touched like matching the rear wings up so there is not a void behind the wheelarch and rear bumper. Also he has added some body sliders. I think its up for sale now he has brought a new motor to play with.
i know its not a disco but its a bobtail ya could do that sort of look and take a look on youtube and you will find a vid on there showing someone bobtailing his ,,..
