You can't use any other radiator and expect proper cooling. It needs to be for the 1987 300D/TD. Get the Behr, not Nissens. The Nissens doesn't have metal reinforced necks for the hoses, and you also will have to cut the plastic tank on the driver's side to make it fit. BT, DT. Expect the cost to be around $300 for a new one. Or, send your old one to Reseda Radiator, then can rebuild them for (last time I checked) $125 plus S&H both ways.
