Well my old Dodge W300 has giant 1480 yokes on the drive shafts and t case. I will have to upgrade my 14 bolt rear and Dana 60 front to the 1480 yoke. Is the Dana 60 front yoke the same as a Dana 60 rear? I am not sure on the jack shaft between the transmission and t case what todo other than change the slip end to match the transmission. But it has to be the exact same length. Or see if I can get a U joint that fits the transmission and shaft with 2 different sizes. Any help is much appreciated.
