Volgens onderstaande link van brickboard zijn deze inderdaad niet meer te krijgen bij de dealer.
Originele maat is 12x20x5 maar 12x20x4 schijnt ook prima te kunnen.
Onderstaande even de copy-paste vanuit de link:

Center Shaft Seal There is a center shaft seal inside the distributor plate that dries out and leaks oil. This shaft seal is hard to find.
Where to Find Center Shaft Seal: [Randy Starkie] Get the entire aftermarket seal kit from FCPGroton for about $3. [Tip from John Sargent] If you have distributor shaft seal leaks in the 700 series with B230 engines (cam driven distributor on rear of head), the distributor o-rings are available from Volvo, but the shaft seal is not. A few weeks ago I even looked in the parts manual, and the shaft seal is not shown. Jim found that Honda part #91205-KF0-003 is a replacement for this seal. It works perfect. However, it is not stocked by many Honda mower dealers, and some want a $7.50 service fee to order a non-stocked part. The seal is about $2.50 US from Honda (#91205-KF0-003 Honda or Transcom #12X20X4TC). This seal is simply a metric seal, 12mm X 20mm X 5mm. It is for a 12mm shaft, it is 20mm OD, and 5mm thick. It is also a rubber coated (that's good) seal with two lips. As near as I can tell, the original seal Volvo used came both rubber coated and non-coated, and appears to be a single lip seal although I can't tell for sure. Now for the substitutions. Chicago Rawhide seal 4701 is exactly the same with a single lip. Transcom seal #12X20X4TC is a double lip seal, rubber coated, that is 4mm thick. That is what is in the distributor in my wife's 745T. When I installed the seal, I set it with the outer edge flush with the distributor housing. There is a 1mm gap behind it which won't hurt anything. You could also set it all the way back in the housing, and it should also be fine. It fits tight, and I doubt that it would ever move out against the seal retainer. The Transcom seal cost $1.82 US from a local bearing sales house. For those of you who can't get those brands of seals, simply contact a bearing supply company and tell them you want a 12mm X 20 mm X 5mm seal, preferably rubber coated with double lips.
