I have recently bought a 1988 90 truck cab 2.5 petrol with 25,000 miles and in absolutely original condition. I have bought an estate top and sides and intend to fit it soon. The question is, at that date, should the rear door have 2 or hinges? I have to buy a new door and there seem to be both options available. The triangular plate that takes the anti Luce catch is nit drilled for a hinge.
