Nate,
That's why we only stock the PML pans and diff covers, their increased fluid volume does the job as far as cooling the fluid as well as the double deep pans that hold 8-10 extra quarts, and they do it for a lots less money too. Plus your average fluid temp is lower as it doesn't take so long to cool all the extra quarts of fluid. Their 2 quart increase does all that is necessary.
