I'm looking at getting the Extreme Duty rear Driveshaft ( #8581 ) but my size isn't listed. for the custom length option do I give the tight measurement from yoke to yoke? (30 3/4 ) or do I need to subtract some, if so how much?

If your size is not an option, choose custom. Give us your working length, vehicle on the ground with weight on it, from center of yoke to center of yoke.
