XJR/6 Radiator Replacement

Is there a source for a new radiator for the XJR/6? Part number MNA4190AA? The plastic lip on the inlet have broken off. My understanding is that it is identical to the XJ6 radiator except for the connects for the trans cooler. So is there an adapter for the connections or can the fittings from the XJR/6 radiator be transferred to the XJ6 radiator?
Thank you.
