Ok, youll need bonnet, lights, guards and bonnet latch. The lights are worht a fair whack of money, so the best way I can see you doing it, is find a car atthe auctions that is written off with tail end damage. Find one without
IRS, and series 2, and youll have a spare gearbox, engine (or transfer the engine) better diff, front end conversion and any other little options, you get with it, all for probably under $2000.
Youll also get lowered suspension, and the series 2/3 brake upgrade.
