Does anyone have a part number for the Transmission Oil Cooler with Supplemental Fan for an 87 300 TDT?

Are these even available any longer? If not, is there some type of alternative? I am going to be changing the tranny fluid and filter soon. I thought this would be a nice upgrade for the desert heat. :-)

Also, do they work on the 87 300 D?

Thank You In Advance!
