Looking for advice on XJ6 overdrive unit speedo drive

I am going through the transmission on my Panther which uses a 1974 XJ6 S2 Type A Laycock overdrive. I removed the brass "bushing" (part 10866 in the parts book) and took off the external o-ring that seals it to the tailshaft housing. Looking inside I saw what looked like another o-ring about halfway down the bore which seals the shaft of the drive gear itself. I went in with a hooked o-ring tool and lo and behold it's a lip seal! A tiny lip seal complete with garter spring. They must have installed it with some arcane magic because it is placed inside a bored o-ring gland and I cannot fathom how they did it.

Long story short, I butchered it trying to remove it while I still thought it was a simple o-ring. It does not show up in any parts book images. I'm actually going to have to go in with a small boring tool on my lathe to get the remainder of the pieces out. I'm hoping the dimensions will be that of a standard o-ring gland and I plan to use one to replace it.

Any experience in this area? Or am I screwed and need to buy a new assembly, which presumably has the lip seal already installed ($112 From SNG).

XK's Unlimited may have it too

The Jag forum is just below us too, so you can check there also.
 
Discovered that it comes apart in two pieces once you drill out a tiny pin. Now have the replacement seal (under $5) and ready to reassemble.
