Utility Land Rover models (Ninety, One Ten and Defender) are unusual vehicles in the modern age because almost everything is bolted together and can therefore be unbolted. This is a boon where a body part needs to be replaced, especially when that part is the main bulkhead.
This early Ninety is 38-years old and suffering major rust issues in the chassis and bulkhead. The bulkhead has serious corrosion in the footwells and the bulkhead feet (where it is bolted to the chassis), rendering the Land Rover structurally unsound. There are also signs of ugly rust damage around the top corners of the bulkhead, below the windscreen where rust is eating its way out from the inside.
Replacement bulkheads are available from Richards Chassis and others, whereas just five years ago it was almost impossible to purchase a good replacement. Nevertheless, it may be possible to repair this bulkhead rather than replacing it but, either way, the front bodywork needs to be removed to investigate fully.
