Hi all - just finishing the details on my axle swap and I have to have the driveshaft shortened.

The rear segment of the drive shaft has a slip yolk on 1 end, bolted to the rear axle on the other. I currently have 1" of travel up on the slip yolk before it bottoms out.

The total length of the splines is 5" so there is 4 inches engaged with no load. I would like to get more "up" travel so I need to shorten the driveshaft but how far do I go? Is there a rule of thumb for slip yolk travel or spline engagement?
