Hi everyone, I have a 1946 chev 1.5 ton dually which didnt have axle shafts in it, went to a couple different places to find some,most of the trucks were early to mid 50s with just a cover and the shaft splined to the hub which wont work so today found a couple 40s trucks that appeared to have correct style,to shorten this up,mine are 10 spline and both sets i pulled are 16 spline, what are they ? 2-ton ?
