Thought it was my diff cover leaking gear oil. Turns out it is the seal where the splined shaft enters the diff.
Anyone know of a source for these? I am not having any luck so far. This is on a 66, not sure if other years are compatible.
Leaking axle seal at diff. (66) New seal needed?

Thanks for the response. I notice I wasn't very clear in my question. The leak is where the drivers side cv-shaft enters the diff. I this still the correct seal.

Re: Leaking axle seal at diff. (66) New seal needed?
Should be... It's the output shaft oil seal... that's what you're talking about to the best of my knowledge. I guess terminology isn't my strong suit, but I'm 80% sure that's the right one....
IIRC, you'll need either the appropriate tool, or a conveniently sized piece of pipe to get it seated propely. But, that's knowledge from my Fiero, I don't know if it translates to the Toronado.

- Years Owned: My first Toronado was a 1968 W-34 with the bucket seats and center console... (weeps gently) It was a New England rustbucket in 1982 after less than 14 years. So sad. But it is what infected me and before I knew it I had another '68, a '69, a '70 and eventually inherited a friend's '67 and another friends '73. After buying my brand new Grand Prix in 1988 I retired the last of my Toronados and pulled the 455 I had rebuilt along the way and put it into storage in a friend's barn where it is to this day.
In Mid September of 2010 I happened to see a repeat of the show where Jay Leno did his 66 Toronado and had an instant remission of the disease which resulted in my purchase of a 1969 in very good condition. I am now in the process of fully rehabilitating it and hope to have it on the road in the spring of 2011. - Location: Gig Harbor, WA

I replaced both of these seals in my car. I removed them carefully - carefully with respect to the housing, not the seals - and used a standard seal tool obtained cheaply at Harbor Freight to install them.
I cannot remember where I got the seals but I think it was at one of my local shops; Oreilly's, Autozone or NAPA. Might have been from an online source; it is possible I ordered them from Applied GMC - http://www.appliedcgmc.com - which is a supplier of parts for the GMC motorhome that was based on the Unified Power Package from the Toronado.

I have my Fuel Injected Toronado. Life is good!
