Not trying to be a wise ass, but what configuration?
Custom built D60 like most run against a stock junkyard D70? Junkyard FF D60 with stock drum brakes? With disc brakes? Junkyard semi-float D60?
I doubt many, if anybody, has actually weighed them, but someone might know where to look. A normal junkyard D60 is 30 spline, while all the semi-float D60's everyone runs are 35 spline. The D70 is 35 spline.
