Chasing info on FJ Holden diffs.
I have three diffs.Making one good one out of three
Two look the same and the third has an oil drainage bung on rear of it
The FJ rims fit both diffs so im guessing they are all FJ but would there be any difference on the internals and outer bearings etc?
is the diff with the bung factory or modified? it looks factory
Diff is going into a Panelvan
