Regan,

If you really wanted to keep the 2-speed, you could install an auxiliary gear box. This would give you overdrive. You might want to look into driveshaft speed at some point. I picked up a spicer 7231 to gain a overdrive for my C50. You'll find that some C60's already have this auxiliary transmission.

Another option is exactly what your thinking about, swap in a different axle. You could probably find an Eaton 19060T (19=19,000lbs, T=two speed) under some medium duty trucks.

I see alot of internationals getting parted out. These usually have an N175 rear end them (17,000lbs, single speed) with a gear ratio 3.90, 4.10, 4.44 (they come in many different ratios).

With both of those axles, you'll probably find them fitted with disc brakes if that matters to you.
