On a Model A with fenders the frame gets crowded on the inside of the frame but there is room on the outside of the frame under the fender apron for a cooler and the front fenders should scoop some air under there which is not part of the flow under the hot engine and exhaust pipes. I presently have a 24" double pass finned cooler there as well as a Derale deep pan made of steel; C9X made the important comment that cast aluminum trans pans will crack easily but a steel one will more likely survive a hit with only a dent. I am not very happy about the fact that the hoses to the cooler pass under the frame but I have put them behind the front four bar mounts for protection. The Derale pan is low but adds over an additional quart of fluid and has cooling tubes running through the pan. In my car the front 5" dropped axle is the lowest part of the car with the engine pan next lowest and the Derale pan is higher than the engine pan. I just purchased the type of finned cooler with the fins arranged along the length of the cooler but it is only 18". I hope to replace the 24" aluminum fragile cooler with the sturdier finned version because my 350 foot long country driveway is pretty rough and I am not sure the fragile cooler could survive a spray of 1 inch gravel stones but then again maybe the shorter 18" cooler will not cool as well as the fragile 24" cooler. Again, I don't have it running yet so I don't know how this will all work out but I am hoping that the extra fluid and cooling fin holes in the Derale pan along with the frame-side cooler will be enough.
