HP dana 44 cut to waggy length.

Ok im just asking for some fabricators that have done this before to chime in here or anyone that can check the accuracy of my research. As the title says im chopping a 78 F250 to 1987 waggy length and building it with some nice goodies. Now to get my lengths right when i cut i need to subtract waggy axle shaft lengths from the for HP axle lengths and whats left is how much i need to remove from the axle tubes on both sides. So according to my calculations passanger side HP shafts are 34.75 minus waggy passenger side of 32.12 with a remaining number of 2.63 and driver side HP is 18.62 minus 15.80 with a remaing number of 2.82. I pretty sure im correct. Please someone comment if my numbers are wrong.

Best way to do this is really a little at time, I make one cut about an inch before what I belive to be my final messurement is. Then I slide the shaft in there and just make sure the tube is still longer than the shaft.

Your numbers look right to me, but play it safe and cut it under. Your close to building a final axle dont rush the cuts as its a somewhat easy repair to add tube but adds to the time and labor of the build.

I always slide a tape measure into the housing and hook it onto the side gear of the diff. Then I measure to the center of the ball joints. I add 1/2" to that and that's the length of your shaft.
