Hi Austin

There are two sizes of axles..... one for the 15 cwt and one for the larger 60 cwt.

First we need to identify the size of your axle...... on top of the steering knuckle..... the small axle has four bolts..... the larger has 6 bolts...

see Picture attached... any CMP axle withthat 4 bolt size will have the saem ration. In addition...on top of the centre gear cluster.... there should be a ratio stamped into the cast iron body..... you may need to clean the area with a stiff wire brush and wet down with light oil to be able to read it.
