"I have been installing wider Radiator Cores in MGA's when restoring same for many years, by using the bottom tank of an MGB which is 2-7/8 inches wide compared to 2 inches for a MGA. Admittedly you have to modify the Radiator Duct Panel to compensate for extra width of bottom tank, but that is no problem when you have a new panel to install or even bending an existing one still in the body. You still use the top tank from the MGA and install an ADRAD 129 NPN 629547 Core and you will never have a problem with over heating".
