Hy Spanky, according to my Canadian parts book the front axle on my 1950 Maple Leaf 1700 series (3 ton) p/n is 5834322, the part number for the 450 GMC is 2229113. The front fenders for the Maple Leaf are p/n 3682482 R.H. for all tires except 9.00X20, p/n 3682481 L.H. for all tires except 9.00X20, for 1947-51 with 9.00X20 tires p/n 5836500 R.H., L.H. p/n 5836499. Fenders for a 450fc p/n 2275893 R.H., L.H. p/n 2275894, I know my Maple Leaf fenders are not as large as those on my 450s hope that helps.
