This pic is just for reference but I had kept this because it represents an original 1966 Mustang 289 engine compartment. This is one of Bob Perkins cars, a very low milage 66' Mustang. This shows the radiator hoses with wire clamps but I do not know the exact build date or plant. Perhaps this would help folks none the less, once the plant/time period can be unearthed. Maybe others here know this info??
