I used generic black o-rings sold by the bag in the
loose parts bin at Pep Boys.  Worked O.K. so far.  I
think both are the same size.  I will try to check the
o-ring and seal sizes today.  If you have access to a
friendly machinist, he can make you a tube about 2.5-3
inches long that tapers from the o.d of the snap ring
loose (uninstalled) to slightly smaller than the o.d.
of the bore it fits into.  This makes installing it
(the toughest part of this job) a snap.  Just set the
snap ring in the tapered tube and push it down with a
deep socket (like 14mm or so) and it will snap right
in.  Takes about 5 seconds, literally.
