Do please post some pictures. I think the charm of these early cars now is in having them in close to original build spec, Ford Crossflow with twin sidedraft twin choke Webers (or a single twin choke downdraft Weber), live axle and 4 speed gearbox, rather than buying one now to extensively modify. I would get it up and running, replace the tyres, flexible fuel and brake hoses, brake pads and shoes, flexible coolant hoses, and give it a good service including replacing oil and antifreeze, new brake fluid, drain the fuel tank, flush out the radiator and heater, new filters - oil, air and fuel, new rotor arm, distributor cap, condenser, plugs and leads, check coil OK, check fuses, clean all earths and electrical connections. Then MoT and use and enjoy. I would not over restore it, just as built and back up to running condition.
If you change your mind, such a project car is always of interest… If you simply restore it it will always be saleable plus you won’t have sunk too much into it.
