Hi guys, the old diff in my partners auto 1200 sedan is giving up the ghost... ive been lucky enough to come across a fully rebuilt H145 for a sedan, (has shock mounts on leaf mount). At the moment the car has a jatco auto (not BW) but it has a borg warner diff. I was wondering when i swap diffs, will i need to put the flange off the BW diff onto the H145?? How else can i do this? Are the input splines different on a standard 4speed compared to a Jatco auto, if so i could just use a coupe tailshaft?? I just want to have it all ready when the time comes to put it in. Cheers Sean
