I recently found another radiator option.
OSC 683
I exchanged emails with them, and they claim it is a drop in replacement for the TR, old diesel cars etc, it has the engine oil cooler, and trans cooler. It is aluminum with plastic end tanks, but the price is no better than allradco.

• Every unit is 100% pressure and fit tested
• All necessary fittings or hardware are included in each unit for an easy install
• The minimum benchmark when designing a new radiator is always the OE standard or an “approved” aftermarket design
•OSC uses double corrugated “Brown Box” to better protect radiator fins during shipping. Most of the units utilize “Blown Foam” technology to further protect the unit from shipping damage.
