Quote:[COLOR="Red"]Early Bronco Dana 44 axle: The came with a Dana 44 starting in 1971, but the Dana 30 can also be found in that year. All EB's had 5-260 style u-joint axles from Ford, they never had the 297 style.. Thus it is a popular option to swap axle shafts for the large size. Most common is to swap the short or stub side, as it is so easy to do. Check main page for axle shaft chart, as it lists the different shafts you can swap in..
, It's a common swap to use an F150 short side shaft to replace the EB shaft. This is to increase the u-joint from a 260 to a 297. The EB shaft is 18 5/16" and the F150 shaft is 18 5/8 to 29/32". Thus it's common for the F150 shaft to be trimmed to fit on the pumpkin side. However the Chevy Dana 44 shaft is 18 1/2" so it would work better as an inner shaft than the F150. Also a Dodge W100 from 1972.5 - 74 with B.O.M. 603413 has the exact same length axle shaft at18 5/16" but with a 297 u-joint![/COLOR]
