Hi Nick thank you for your response I think you for whatever reason are looking at this through the wrong end of the telescope a good quality radiator should not fail after 4 years forget the mileage the original fitted to the car managed 10 years when the replacement was fitted I did not specify and aluminium radiator that was Aero Racing decision I am unable to understand why you feel 4 years is a reasonable period the next meeting I attend I will seek the opinion of other owners and ask them to view the offending radiator.
As a matter of interest are you a Morgan Dealer
