Been working on building my front Dana 44 for the Jeepster and ran into a snag. As far as I could find, nobody offers an axle upgrade "kit" for chromoly shaft upgrade. They have to be sourced individually. So I did some digging around and managed to match shaft lengths/splines with part numbers through YUKON AXLE. I'm posting them here in hopes of saving some time and frustrations for fellow Jeepers.
These numbers pertain ONLY to the WIDE TRACK DANA 44 front found under the J-10 and CHEROKEE CHEIFS, as they are 2 inches wider on both sides.
Stock Spicer replacement right side p/n 660091-5
YUKON chromoly right side p/n YA-W38823 (16.5" length)
Stock Spicer replacement left side p/n 660091-6
YUKON chromoly left side p/n YA-W38824 (35.25" length)
outers are same for 19 spline Dana 44 chevy, dodge, jeep, ford.
YA-W38815 (9.94" length)
Hope this helps someone else. Cheers!!
