Pretty basic question right? Never had this issue before.
In the process of rebuilding a late Aug 1937 diff but have discovered that there is no provision for a filler plug. The RH diff housing has no plug for a filler in fact no boss provided in the standard position. It would seem that the LH housing may be not original to the diff but it is a semi Girling housing.
Does the later Girling diffs have a filler in the LH housing? Can someone please tell me the type of thread and plug and where is it positioned? A photo for positioning would be most useful if someone has access to a similar diff.
I removed this diff from a car I was restoring about 10 years ago and I'm guessing that it never had an oil change since a rebuild somewhere in the 60's as you would need to take the diff out of the car, invert and fill through the drain plug.
Thanks to those who may respond to my dilemma.
