Yes, there is Ken. You can install the Derale 32 inch High-Output, Electric Radiator Fan-and-Shroud Assembly - 4,000 CFM, item # D16934. It is designed as a universal application so you'll need to measure to be sure there is room to mount the assembly behind the radiator. I have listed the dimensions below:
Width - 31-3/8"
Height - 15-3/4"
Overall Depth - 3-1/4"
Mounting Holes - 12-7/8" Top to Bottom
Mounting holes - 28-7/8" Side to Side
You will also need two turn-on sources, one for each fan. You could use two Derale Lighted On/Off Switch for Electric Fans, item item # D16740, or one of these switches and a Derale Adjustable Fan-Control Thermostat with Radiator Hose Probe, item # D16769. If you wanted both fans to come on thermostatically you can use two of the Derale Adjustable Fan-Control Thermostat with Radiator Hose Probe, item # D16769.
