47-54 chevy dropped axle

anyone know just what the difference is between the 3/4 ton and 1/2 ton front axle and spindles, or better yet post the measurement of the king pin diameter and boss thickness
of a 1/2 ton. I know the track width is the same, and if its just larger king pins i could bore out a classic performance 3" dropped 1/2 ton axle to fit the 3/4 ton spindles, I don't want to have to use 1/2 ton spindles as I have already setup the ones i have with disc brakes.
thanks

I know that for stock axles:
The 3/4 Ton axles are built to take larger king pins and heavier spindles.
You could not put 3/4 ton spindles on 1/2 Axles safely, even if by machining you could make it fit.
Also the locking pins wouldn't work.
So I wouldn't try it. It might be unsafe.
I don't have the exact measurements for the king pin diameters, but as I remember for the 1/2 tons it is about .86 inches. The 3/4 Tons have about a 1.10 in diameter.
You might simply consider using a stock 3/4 Ton front axle. It should fit the 1/2 ton truck. The connecting rod to the steering column should be the same for 3/4 and 1/2 tons
You can take the 3/4 ton axles to one of those heavy truck repair outfits and they will install new king pins. They are probably too difficult to install without special equipment.
