I recently heard that an individual acquired a complete AL radiator for a R107, noting that all components were properly positioned and the connections were secure; nonetheless, the radiator was slightly oversized and did not fit inside the radiator support.
That is too high for only a recore. You may send it to Detroit and significantly reduce costs. Four Seasons Radiator in Madison Heights, MI serviced my Mercedes-Benz and fabricated a bespoke radiator for me; both remain exceptional. They requested about $600 for an AC condenser, but I located one for $350.
