hey guys, i'm in the middle of a diff swap. i'm putting a 3.89 ratio from an R31 syline diff into an EB series II diff (currently 3.27). my problem at the moment is getting the tailshaft flange off the skyline diff (yes i know its not a ford but its a borg warner 78 diff just like the fords) and i'm going to have the same problem when i come to pulling the EB diff apart. so how do i get these flanges off. i've got the retaining nut undone and i've tried knocking the pinion shaft thru the flange and knocking the flange off the splined shaff and neither have worked. i drowned the spline in WD40/RP7 tonite so i'm gonna have another go tomorrow.
are there any tricks or have i forgotten something? here are some pics of the skyline diff's flange:
