The stock front axles 30 spline in the M715...dont know on the chevy.
The rear is 23 spline, Dana 70...all the 70's have the number 70 cast on the housing,visible from the rear in the area just to the side of the cover on a wedge shaped reinforcer plate from the center section to the axle tube...if the one you have is not a 70...stock chevy probably not, I wouldnt think there would be any interchange there.
