What is the ratio? Is your ‘52 10 bolt or 6 bolt? If it matches your front axle, and everything matches up like you say, the ratio would be the determining factor, assuming it is not worn out.
Are your front hubs bolted on or pipe thread? If bolted on, you could install disc front spindles from a P30 or P3500 HD GMC front axle.
