My 59 has 74 front and rear axles. As you can see from the photo with skinny tires (7.50 x 16 in that photo) the outside is just even with the vertical front fender and rear bed sides. Any wider tires or "dished" rims and your tires are outside of the fenders, which means rocks, dirt, etc. will be kicked up on the side. In some states you need to run full flares if the tires stick out beyond the fender. If you do a search you will find some trucks on the C series frames.
