Picked up a diff today, not exactly what I had planned on, was a bit out of nowhere but it could work ok, especially for the price it was....
I picked a E series leaf diff ( Liteace diff). It has a locked centre and bigger drums....... Has been running in a 18RG KE30. I've measured up the leaf mounts, and they are the same spacing as the AE71 panelvan diff. The overall width of the diff is actually shorter, but I will be running neg offset wheels, so it shouldn't be a problem....
For those that dont know about E series, they are a size between T series and F series. They are a 7.1" diff. (F series are 7.5"). The problem with these diffs, is that there was never an LSD availiable for them, but they were put behind 6cyl, so they should be strong enough,....
