When shortening a full width front axle, everything comes off the long side. Dont touch the short side. Putting the pumkin to far to the short side causes a slew of issues. The longer the short side the better. That is why the most populay hp 60's and 44's are the ones from the 78-79 fords. They have the longest short of all the other hp ford 60's and 44's.
If you find your axle at randy's, you can find another factory 44 shaft length that may work for your cut down. For instance if your long side inner is 34", maybe they have a factory application that measures 30" or close to it. You could do your shortening based on available stock lengths.
Or you can always go full custom on shafts as well. Not the end of the world.
