I have a 1974 f-250 4X4 highboy with the front drum brakes and power assist steering. I am considering the purchase of a complete front axle assembly and steering box off of a 79 f-250. The 79 has a "high pinion" dana 44. This brings me to my question! Does anyone know if the front driveshaft rotation direction is the same for a 1974 f-250 (highboy) which has a low pinion heavy duty dana 44 as a 1979 f-250 with a high pinion dana 44????? Has anyone ever done this? Do all 79's have the high pinion front axle?
